Ferrotoroidic polarons in antiferrodistortive SrTiO3

Takahiro Shimada, Yuuki Ichiki, Gen Fujimoto, Le Van Lich, Tao Xu, Jie Wang, and Hiroyuki Hirakata

Phys. Rev. B 101, 214101 (2020) - Published 1 June, 2020

Discovery of new quasiparticles with nontrivial topological field textures, such as polar vortices, skyrmions, and merons, holds promise in technological paradigms. Here, the authors demonstrate a ferroelectric quasiparticle with topological polarization vortices by engineering excess electron polarons. They further show that the electron polaron carries a magnetic moment coupled with ferrotoroidicity, i.e., the magnetoelectric effect. This result provides insight into the ultimate miniaturization of ferrotoroic materials and a new class of functional polaron families.

Subkilohertz optical homogeneous linewidth and dephasing mechanisms in Er3+:Y2O3 ceramics

Rikuto Fukumori, Yizhong Huang, Jun Yang, Haitao Zhang, and Tian Zhong

Phys. Rev. B 101, 214202 (2020) - Published 8 June, 2020

Rare-earth dopants in solids are conducive of sharp optical transitions and long spin coherence at cryogenic temperatures. While superb coherences are routine in high-quality bulk crystals, the more versatile materials such as rare-earth doped nanoparticles and ceramics have suffered from excessive decoherence due to disorder. This work reports a surprisingly narrow linewidth of Er in Y2O3 ceramics made with industry-standard synthesis technique, putting it on par with the best single crystalline counterpart. The ultranarrow linewidth also helps clarify decoherence pathways within the matrix.

Nonexistence of the decahedral Si20H20 cage: Levinthal's paradox revisited

Deb Sankar De, Bastian Schaefer, Bernd von Issendorff, and Stefan Goedecker

Phys. Rev. B 101, 214303 (2020) - Published 1 June, 2020

For C60, the potential energy surface exhibits a driving force toward the ground state that allows it to be found rapidly. However, the potential energy surface of a cluster can also exhibit features that prevent us from finding its global minimum. In the case of decahedral Si20H20, which is a theoretically postulated stable ground state but was never synthesized, there is no driving force towards the global minimum. The system visits a huge number of low energy structures during its evolution without ever falling into the global minimum. This is exactly the scenario described by Levinthal in his famous paradox about protein folding.

Electric field controllable high-spin SrRuO3 driven by a solid ionic junction

Jingdi Lu, Liang Si, Xiefei Yao, Chengfeng Tian, Jing Wang, Qinghua Zhang, Zhengxun Lai, Iftikhar Ahmed Malik, Xin Liu, Peiheng Jiang, Kejia Zhu, Youguo Shi, Zhenlin Luo, Lin Gu, Karsten Held, Wenbo Mi, Zhicheng Zhong, Ce-Wen Nan, and Jinxing Zhang

Phys. Rev. B 101, 214401 (2020) - Published 1 June, 2020

A high-spin ruthenate phase is achieved at the SrRuO3/SrTiO3 interface via a solid ionic chemical junction, which benefits from the distinct formation energies and diffusion barriers of oxygen vacancies across the heterostructure. This high-spin SrRuO3 phase can be reversibly switched by electric field in a solid-state ionic gating device, providing a framework for atomic design of controllable functionalities in strongly correlated oxides using solid-chemistry tools.

Pressure-induced suppression of ferromagnetism in the itinerant ferromagnet LaCrSb3

Z. E. Brubaker, J. S. Harvey, J. R. Badger, R. R. Ullah, D. J. Campbell, Y. Xiao, P. Chow, C. Kenney-Benson, J. S. Smith, C. Reynolds, J. Paglione, R. J. Zieve, J. R. Jeffries, and V. Taufour

Phys. Rev. B 101, 214408 (2020) - Published 3 June, 2020

The experimental characterization of materials under high pressure is often limited to a few properties. Usually, this is insufficient for a detailed understanding of the underlying physics. Here, the authors report a suite of high-pressure experiments probing the ferromagnetic state in LaCrSb3. They assess the Curie temperature, crystal structure, and evolution of the magnetic moment as obtained from the integrated absolute difference in x-ray emission spectroscopy. The Curie temperature appears to be driven by the Cr moment, which decreases smoothly in contrast to the pair of steplike decrease features predicted by density functional theory.

Softening of breathing elastic mode and trigonal elastic mode in the disordered pyrochlore magnet NaCaCo2F7

T. Watanabe, H. Kato, Y. Hara, J. W. Krizan, and R. J. Cava

Phys. Rev. B 101, 214425 (2020) - Published 15 June, 2020

Here, the authors perform ultrasound velocity measurements in the frustrated pyrochlore fluoride NaCaCo2F7, which exhibits spin freezing below Tf 2.4 K with the inherent presence of exchange disorder. In this cubic magnet, the bulk modulus and the trigonal shear modulus exhibit anomalies at temperatures below 20 K down to Tf, which reveal an occurrence of magnetic field induced crossover from an isostructural lattice instability toward the spin freezing to a trigonal lattice instability arising from the emergent dynamical spin-cluster state.

Tomography of basic magnetic domain patterns in ironlike bulk material

R. Schäfer and S. Schinnerling

Phys. Rev. B 101, 214430 (2020) - Published 18 June, 2020

The magnetic domains in bulk nontransparent magnetic specimens are not accessible by simply slicing the sample as the domains would immediately adapt to the new surface. Therefore tomographic imaging tools are required to disclose the complete domain structure. In this paper Libovicky tomography is applied to reveal the true three-dimensional structure of characteristic domain patterns in an ironlike material, which previously have been vaguely analyzed only by surface domain observation and by using arguments from domain theory to infer the inner domains.

Superconductivity and topological aspects of the rocksalt carbides NbC and TaC

T. Shang, J. Z. Zhao, D. J. Gawryluk, M. Shi, M. Medarde, E. Pomjakushina, and T. Shiroka

Phys. Rev. B 101, 214518 (2020) - Published 18 June, 2020

Superconducting materials with a nontrivial band structure are promising candidates in the search for topological superconductivity. The rocksalt carbides NbC and TaC are two fully gapped superconductors with relatively high critical temperatures (Tc = 11.0 and 10.3 K, respectively). They exhibit three closed node lines in the bulk band structure protected by time-reversal and space-inversion symmetry. By combining muon spin rotation and relaxation investigations with theoretical calculations, the authors demonstrate that rocksalt NbC is a potential topological superconductor.

Exotic interband pairing in multiband superconductors

K. V. Samokhin

Phys. Rev. B 101, 214524 (2020) - Published 29 June, 2020

The electron Bloch states in crystals with spin-orbit coupling do not always transform under symmetry operations in the same way as the pure spin-½ states. This has profound consequences for the gap symmetry of superconductors. In conventional s-wave superconductors, the interband pairing exhibits unconventional features, such as triplet components and odd parity; it can produce line nodes in the excitation energy gap. In d-wave superconductors, the interband pairing changes the positions and topology of the lines of the gap nodes.

Phys. Rev. B 101, 214518 (2020) - Published 18 June, 2020

Superconducting materials with a nontrivial band structure are promising candidates in the search for topological superconductivity. The rocksalt carbides NbC and TaC are two fully gapped superconductors with relatively high critical temperatures (Tc = 11.0 and 10.3 K, respectively). They exhibit three closed node lines in the bulk band structure protected by time-reversal and space-inversion symmetry. By combining muon spin rotation and relaxation investigations with theoretical calculations, the authors demonstrate that rocksalt NbC is a potential topological superconductor.

Exotic interband pairing in multiband superconductors

Phys. Rev. B 101, 214524 (2020) - Published 29 June, 2020

The electron Bloch states in crystals with spin-orbit coupling do not always transform under symmetry operations in the same way as the pure spin-½ states. This has profound consequences for the gap symmetry of superconductors. In conventional s-wave superconductors, the interband pairing exhibits unconventional features, such as triplet components and odd parity; it can produce line nodes in the excitation energy gap. In d-wave superconductors, the interband pairing changes the positions and topology of the lines of the gap nodes.
