Resistive Measurements of the Upper Critical Fields for Bi-Sr-Ca-Cu-O Thin Films in Pulsed Magnetic Fields
The magnetoresistance of c-axis oriented Bi-Sr-Ca-Cu-O thin films were measured in pulsed magnetic fields up to 40T. There are conspicuous differences between B ⊥ c and B//c cases. In case of B//c, the resisti...

Observation of the First-Order Vortex Lattice Melting in NdBa2Cu3O7-y Single Crystals
We have observed the first-order melting transition for the first time in twinned NdBa2Cu307-y single crystal that was previously thought to be a non-stoichiometric system. The transition displays a ‘kink‘ in res...
