Systematic Investigation of Anisotropic Magneto–Peltier Effect and Anomalous Ettingshausen Effect in Ni Thin Films

In the field of spin caloritronics, direct observations of the anisotropic magneto-Peltier effect and the anomalous Ettingshausen effect (magneto-thermoelectric effects appearing in magnetic materials) have recently been reported. This work establishes a procedure for the pure detection of these phenomena in thin films, and clarifies the important role of sample dimensions and thermal boundary conditions in the measurements. The findings reported here will invigorate research on the physics and materials science of spin caloritronics, and will develop nanoscale thermal-management technologies based on magneto-thermoelectric effects.
