Multiple broken symmetries in striped La2−xBaxCuO4 detected by the field-symmetric Nernst effect
We report a thermoelectric investigation of the stripe and superconducting phases of the cuprate La2−xBaxuO4 near x=1/8. We vary the doping and the magnetic field to identify features in the field-symmetric Nernst effect ...
A disorder-enhanced quasi-one-dimensional superconductor
A powerful approach to analysing quantum systems with dimensionality d>1 involves adding a weak coupling to an array of one-dimensional (1D) chains. The resultant quasi-1D (q1D) systems can exhibit long-range order at low ...
Interfacial effects revealed by ultrafast relaxation dynamics in BiFeO3/YBa2Cu3O7 bilayers
The temperature dependence of the relaxation dynamics in the bilayer thin film heterostructure composed of multiferroic BiFeO3 (BFO) and superconducting YBa2Cu3O7 (YBCO) grown on a (001) SrTiO3 substrate is studied by a ...
Hysteretic magnetoresistance and unconventional anomalous Hall effect in the frustrated magnet TmB4
We study TmB, a frustrated magnet on the Archimedean Shastry-Sutherland lattice, through magnetization and transport experiments. The lack of anisotropy in resistivity shows that TmB4 is an electronically three-dimensional ...
