Anomalous Nernst and anisotropic magnetoresistive heating in a lateral spin valve

We measured the anomalous Nernst effect and anisotropic magnetoresistive heating in a lateral multiterminal permalloy/copper spin valve using all-electrical lock-in measurements. To interpret the results, a threedimensional thermoelectric finite-element model is developed. Using this model, we extract the heat profile which we use to determine the anomalous Nernst coefficient of permalloy R-N = 0.13 and also determine the maximum angle theta = 8 degrees of the magnetization prior to the switching process when an opposing noncollinear 10 degrees magnetic field is applied.
