The structure of domain walls is of interest to the antiferromagnetic spintronics. Here the authors find an additional contribution to the Hall conductivity tensor and a transverse magnetization generated by domain walls in Mn3Sn and report that the

Thermopower across the phase diagram of the cuprate La1.6−xNd0.4SrxCuO4 : Signatures of the pseudogap and charge density wave phases

Cuprate high-temperature superconductors universally exhibit a phase of charge order and a mysterious pseudogap phase. Using thermopower measurements, the authors explore here how the cuprate La${}_{1.6\ensuremath{-}x}$Nd${}_{0.4}$Sr${}_{x}$CuO${}_{4

Room-temperature metallicity of lightly doped SrTiO$_3$ is puzzling, because the combination of mobility and the effective mass would imply a mean-free-path (mfp) below the Mott Ioffe Regel (MIR) limit and a scattering time shorter than the Planckian

The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which sets in at a doping $p^*$ that is material-dependent. What determines

The thermal conductivity $\kappa$ of the cuprate superconductor La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$ was measured down to 50 mK in seven crystals with doping from $p=0.12$ to $p=0.24$, both in the superconducting state and in the magnetic field-induce
