    Step-like negative differential resistance is observed in patterned Pr0.65(Ca0.75Sr0.25)0.35MnO3 structures with mesoscopic (micrometer) length scales. Key to the appearance of the steps is a field- and temperature-dependent mixture of ferromagnetic metal (FMM) and charge ordered insulating...

    The magnetoconductance of nominally identical, 2-μm-long, Au lines has been measured. A 0.7-μm-diam loop was attached to the end of one of the lines outside the probes in such a way that classically no current would flow through it. As expected, the line by itself showed only aperiodic...

An adequate description of mesoscopic superconductivity is obtained by introducing a nonrelativistic version of Grassmann...
