Local charge and spin currents in magnetothermal landscapes.

A scannable laser beam is used to generate local thermal gradients in metallic (Co2FeAl) or insulating (Y3Fe5O12) ferromagnetic thin films. We study the resulting local charge and spin currents that arise due to the anomalous Nernst effect (ANE) and the spin Seebeck effect (SSE), respectively. In the local ANE experiments, we detect the voltage in the Co2FeAl thin film plane as a function of th...

Spin-polarized transport in low-dimensional systems

Superconductivity in a spin-ladder cuprate.

Schön et al. (1) claimed to have shown that a two-dimensional structure is not needed to support cuprate superconductivity. Based on the references for the structure of the film provided in their article, however, we believe that this conclusion is premature. In their report on the field-effect-induced modulation of transport properties in thin films of the spin-ladder compound [CaCu2O3]4, Schö...
