Platform of chiral Majorana edge modes and its quantum transport phenomena
James Jun He, Tian Liang, Yukio Tanaka +1
We propose a method to create two-dimensional topological superconductors with a heterostructure of ferromagnet (FM), topological insulator (TI) thin film and superconductor, in wh…
Z topology and superconductivity from symmetry lowering of a 3D Dirac Metal AuPb
Leslie M. Schoop, Lilia S. Xie, Ru Chen +12
3D Dirac semi-metals (DSMs) are materials that have massless Dirac electrons and exhibit exotic physical properties It has been suggested that structurally distorting a DSM can cre…
The magnetic phase diagram of underdoped YBa2Cu3Oy inferred from torque magnetization and thermal conductivity
Fan Yu, Max Hirschberger, Toshinao Loew +11
Strong evidence for charge-density correlation in the underdoped phase of the cuprate YBa2Cu3Oy was obtained by nuclear magnetic resonance (NMR) and resonant x-ray scatter- ing. Th…
Effect of doping on the magnetostructural ordered phase of iron arsenides: A comparative study of the resistivity anisotropy in the doped BaFeAs with doping into three different sites
Shigeyuki Ishida, Masamichi Nakajima, Tian Liang +8
In order to unravel a role of doping in the iron-based superconductors, we investigated the in-plane resistivity for BaFeAs doped at either of the three different lattice s…
Anisotropy of the in-plane resistivity of underdoped Ba(FeCo)As superconductors induced by impurity scattering in the antiferromagnetic orthorhombic phase
S. Ishida, M. Nakajima, T. Liang +8
We investigated the in-plane resistivity anisotropy for underdoped Ba(FeCo)As single crystals with improved quality. We demonstrate that the anisotropy in resis…
Manifestations of multiple-carrier charge transport in the magnetostructurally ordered phase of undoped BaFeAs
S. Ishida, T. Liang, M. Nakajima +10
We investigated the transport properties of BaFeAs single crystals before and after annealing with BaAs powder. The annealing remarkably improves transport properties, in p…
