Spin wave propagation in a uniformly biased curved magnonic waveguide

A. V. Sadovnikov, C. S. Davies, V. V. Kruglyak, D. V. Romanenko, S. V. Grishin, E. N. Beginin, Y. P. Sharaevskii, and S. A. Nikitov

Phys. Rev. B 96, 060401(R) (2017) - Published 1 August, 2017

Using a combination of experiment and simulation, the authors have investigated comprehensively how the spin-wave transmission across a curved magnonic waveguide is modified through rotation of an externally delivered uniform magnetic field. They reveal that, while the spin-wave transmission is reasonable when the bend is magnetized along an axis of symmetry, the transmission can be substantially improved (by a factor of 2) through just rotating the magnetic field by 15° in a particular direction. To explain their results, the authors study the landscape of the internal magnetic field spanning the structure, and discuss how it can be tuned in order to optimally distribute the flow of anisotropic spin waves across networks of magnonic waveguides.

Chirality-mediated bistability and strong frequency downshifting of the gyrotropic resonance of a magnetic vortex due to dynamic destiffening

Manu Sushruth, Jasper P. Fried, Abdelmadjid Anane, Stephane Xavier, Cyrile Deranlot, Vincent Cros, and Peter J. Metaxas

Phys. Rev. B 96, 060405(R) (2017) - Published 7 August, 2017

The gyrotropic resonance frequency of a magnetic vortex, widely studied for applications in data storage and radio-frequency signal processing, increases with the vortex core’s stiffness. In traditional disk-shaped elements, this stiffness increases if the core is shifted towards the element’s edges. Here, the authors show that introducing a flat edge into a disk locally de-stiffens the core, resulting in the resonant frequency strongly decreasing when the core approaches the element’s flat edge. By controllably displacing the core within the disk one can thus both increase or decrease the core’s resonant frequency with respect to its value when unshifted. This has the effect of more than doubling the accessible range of resonant frequencies. However, more fundamentally, the above properties lead to a chirality-mediated bistability: for a given finite static in-plane magnetic field, one of two values of gyrotropic frequencies can be observed depending on the vortex chirality.

Pressure-induced superconductivity up to 13.1 K in the pyrite phase of palladium diselenide PdSe2

The family of transition-metal dichalcogenides provides a rich platform for studying the interplay between the crystal structure and electronic properties in strongly correlated electron systems. Applying external pressure as a tuning parameter, the authors observed a striking correlation between the critical temperature Tc for superconductivity and the strength of the Se-Se bonds in the high-pressure pyrite phase of PdSe2. The bond length of the Se2 dimer was identified as the main parameter for controlling the superconductivity in the pyrite structure. Strong pressure-induced enhancement of Tc up to its maximum value of 13.1 K cannot, however, be explained solely by phonon softening, and this implies the relevance of additional factors influencing Tc. Indeed, electronic band calculations reveal the presence of topologically nontrivial states in the pyrite structure.

Quantum and frustrated magnets are a great platform to probe collective phenomena of fundamental and technological importance. Antiferromagnets on a diamond lattice have not been as extensively studied as other model magnetic materials due to the absence of obvious geometrical frustration. This is changing with the prediction — and in some cases observation — of several unique phenomena in magnetic A-site spinels like, e.g., degenerate spin spirals, spin-orbital entanglement and topological paramagnetism. In this work, the authors add two model materials to the growing family of diamond lattice antiferromagnets: CuRh2O4 and CoRh2O4. The authors deploy an arsenal of experimental and theoretical techniques to develop a detailed understanding of their results. Their work evidences that CoRh2O4 is a canonical diamond-lattice antiferromagnet while CuRh2O4 displays an unexpected spin-helix ground-state with a very strong influence from quantum fluctuations.

Griffiths singularities in the random quantum Ising antiferromagnet: A tree tensor network renormalization group study

Yu-Ping Lin, Ying-Jer Kao, Pochung Chen, and Yu-Cheng Lin

Phys. Rev. B 96, 064427 (2017) - Published 21 August, 2017

Rare events can have major effects on quantum matter. Extremely unlikely events cause certain physical properties to diverge to infinity near the quantum phase transition of the disordered Ising antiferromagnet in a transverse field, but destroy criticality of the clean system completely when a longitudinal component of the field is present. Using a tree tensor network renormalization group method combined with a novel matrix product operator representation, the authors detect signatures of rare events and determine the zero-temperature phase diagram of the disordered antiferromagnetic Ising chain in the presence of both longitudinal and transverse magnetic fields. The numerical technique used in this paper is generalizable to more complicated many-body systems and higher dimensions.

Magnetic hexadecapole order and magnetopiezoelectric metal state in Ba1xKxMn2As2

Phys. Rev. B 96, 064432 (2017) - Published 28 August, 2017

Odd-parity magnetic multipole order, where time-reversal and space-inversion symmetries are spontaneously broken, may open a new paradigm in the fields of multipole physics, multiferroics, and spintronics. BaMn2As2 is a new candidate material. Here, the authors theoretically identify that the seemingly simple antiferromagnetic order in BaMn2As2 is actually magnetic hexadecapole order mixed with magnetic quadrupole order. Interestingly, doping hole carriers realize an itinerant odd-parity magnetic multipole order. Emergent electromagnetic responses, such as magnetoelectric effect, antiferromagnetic Edelstein effect, and electric current-induced nematicity, are clarified. In particular, the current-induced nematicity is a characteristic response of an itinerant magnetic hexadecapole state and indicates a novel phase, the “magnetopiezoelectric metal”.

Resistance-area product and size dependence of spin-torque switching efficiency in CoFeB-MgO based magnetic tunnel junctions

J. Z. Sun

Phys. Rev. B 96, 064437 (2017) - Published 30 August, 2017

Magnetic tunnel junctions have seen active development for spin-transfer-torque based magnetic random access memory (STT-MRAM), a new technology attractive for low-power applications, especially when embedded in semiconductor logic processors. Such efforts open new frontiers for materials and device physics involving interface magnetic states and materials properties, such as an unexpected dependence of spin-torque switching efficiency on a tunnel junction’s resistance-area product. This paper examines the observation and some possible causes. An experiment-based understanding will improve device performance for wider adaptation, while at the same time deepening the knowledge about magnetic excitations and materials physics.

Their work evidences that CoRh2O4 is a canonical diamond-lattice antiferromagnet while CuRh2O4 displays an unexpected spin-helix ground-state with a very strong influence from quantum fluctuations.

Rare events can have major effects on quantum matter. Extremely unlikely events cause certain physical properties to diverge to infinity near the quantum phase transition of the disordered Ising antiferromagnet in a transverse field, but destroy criticality of the clean system completely when a longitudinal component of the field is present. Using a tree tensor network renormalization group method combined with a novel matrix product operator representation, the authors detect signatures of rare events and determine the zero-temperature phase diagram of the disordered antiferromagnetic Ising chain in the presence of both longitudinal and transverse magnetic fields. The numerical technique used in this paper is generalizable to more complicated many-body systems and higher dimensions.

Magnetic hexadecapole order and magnetopiezoelectric metal state in Ba1xKxMn2As2

Phys. Rev. B 96, 064432 (2017) - Published 28 August, 2017

Odd-parity magnetic multipole order, where time-reversal and space-inversion symmetries are spontaneously broken, may open a new paradigm in the fields of multipole physics, multiferroics, and spintronics. BaMn2As2 is a new candidate material. Here, the authors theoretically identify that the seemingly simple antiferromagnetic order in BaMn2As2 is actually magnetic hexadecapole order mixed with magnetic quadrupole order. Interestingly, doping hole carriers realize an itinerant odd-parity magnetic multipole order. Emergent electromagnetic responses, such as magnetoelectric effect, antiferromagnetic Edelstein effect, and electric current-induced nematicity, are clarified. In particular, the current-induced nematicity is a characteristic response of an itinerant magnetic hexadecapole state and indicates a novel phase, the “magnetopiezoelectric metal”.

Magnetic tunnel junctions have seen active development for spin-transfer-torque based magnetic random access memory (STT-MRAM), a new technology attractive for low-power applications, especially when embedded in semiconductor logic processors. Such efforts open new frontiers for materials and device physics involving interface magnetic states and materials properties, such as an unexpected dependence of spin-torque switching efficiency on a tunnel junction’s resistance-area product. This paper examines the observation and some possible causes. An experiment-based understanding will improve device performance for wider adaptation, while at the same time deepening the knowledge about magnetic excitations and materials physics.
