Wing structure in the phase diagram of the Ising ferromagnet URhGe close to its tricritical point investigated by angle-resolved magnetization measurements

Shota Nakamura, Toshiro Sakakibara, Yusei Shimizu, Shunichiro Kittaka, Yohei Kono, Yoshinori Haga, Jiří Pospíšil, and Etsuji Yamamoto

Phys. Rev. B 96, 094411 (2017) - Published 11 September, 2017

The ferromagnetic quantum phase transition (FMQPT) in clean metals has attracted much interest since a first-order transition is commonly observed. The orthorhombic Ising ferromagnet URhGe provides an excellent opportunity to study the FMQPT, because its Curie temperature can be tuned to zero by applying a magnetic field H parallel to the b axis, perpendicular to the spontaneous moment that aligns along the c axis. Here, the authors perform high-precision angle-resolved magnetization measurements on URhGe to investigate the FMQPT with H applied near the b axis. They find a clear first-order transition below a tricritical point (TCP) located above 4 K, and determine the detailed profiles of the wing structure of the first-order transition in the T-Hb-Hc phase diagram. The obtained wing structure is consistent with the theoretical expectation that three second-order transition lines merge tangentially at TCP.

Theory of the magnon-mediated tunnel magneto-Seebeck effect

Benedetta Flebus, Gerrit E. W. Bauer, Rembert A. Duine, and Yaroslav Tserkovnyak

Phys. Rev. B 96, 094429 (2017) - Published 25 September, 2017

In the tunnel magneto-Seebeck effect, a temperature gradient generates an electric voltage over a nonmagnetic tunnel barrier between two magnetic films that depends on the relative orientation of the magnetizations. This effect has been modeled in the past by the single-electron picture as implemented in band structure calculations. Here, the authors depart from this interpretation and investigate the thermoelectric response induced by electron-magnon interactions. The importance of collective magnetic effects found in the present study challenges the conventional single-electron model for the thermopower of magnetic tunneling junctions.

Optical signatures of the superconducting Goldstone mode in granular aluminum: Experiments and theory

Phys. Rev. B 96, 094514 (2017) - Published 15 September, 2017

In ordinary superconductors the two collective modes of the complex order parameter are usually strongly resilient to the spectroscopic observation. The amplitude or Higgs mode is weakly coupled to the electromagnetic field and it overlaps with the continuum of single-particle excitations at 2Δ, which buries its signal. The phase or Goldstone mode is optically inert, and it is boosted to the plasma frequency by Coulomb interactions. In the present work, terahertz experiments and theoretical calculations are combined in order to demonstrate the existence of an alternative route for the optical visibility of the Goldstone mode in a nanostructured granular Al thin film. The Coulomb screening due to the grains self-capacitance and the intrinsic inhomogeneity of the local superfluid stiffness due to shell effects lead to finite-frequency subgap absorption of the phase modes, showing that nanograins arrays are a promising setting to control the Goldstone mode via optical means.

Inflated nodes and surface states in superconducting half-Heusler compounds

C. Timm, A. P. Schnyder, D. F. Agterberg, and P. M. R. Brydon

Phys. Rev. B 96, 094526 (2017) - Published 26 September, 2017

The half-Heusler superconductors such as YPtBi are multiorbital systems with both strong spin-orbit coupling and broken inversion symmetry. The spin-orbit coupling allows for the formation of Cooper pairs with effective spins larger than unity, which introduces novel pairing states. Some of these states display Fermi surfaces of Bogoliubov quasiparticles. On the other hand, the absence of inversion symmetry leads to topologically protected nodes associated with specific surface features as, for example, flat bands. The authors consider two likely pairing symmetries for this material, one that breaks time-reversal symmetry and one that does not, and find a rich variety of bulk nodes and surface states.

In ordinary superconductors the two collective modes of the complex order parameter are usually strongly resilient to the spectroscopic observation. The amplitude or Higgs mode is weakly coupled to the electromagnetic field and it overlaps with the continuum of single-particle excitations at 2Δ, which buries its signal. The phase or Goldstone mode is optically inert, and it is boosted to the plasma frequency by Coulomb interactions. In the present work, terahertz experiments and theoretical calculations are combined in order to demonstrate the existence of an alternative route for the optical visibility of the Goldstone mode in a nanostructured granular Al thin film. The Coulomb screening due to the grains self-capacitance and the intrinsic inhomogeneity of the local superfluid stiffness due to shell effects lead to finite-frequency subgap absorption of the phase modes, showing that nanograins arrays are a promising setting to control the Goldstone mode via optical means.

The half-Heusler superconductors such as YPtBi are multiorbital systems with both strong spin-orbit coupling and broken inversion symmetry. The spin-orbit coupling allows for the formation of Cooper pairs with effective spins larger than unity, which introduces novel pairing states. Some of these states display Fermi surfaces of Bogoliubov quasiparticles. On the other hand, the absence of inversion symmetry leads to topologically protected nodes associated with specific surface features as, for example, flat bands. The authors consider two likely pairing symmetries for this material, one that breaks time-reversal symmetry and one that does not, and find a rich variety of bulk nodes and surface states.
