Recently, spin-caloritronic effects have attracted great interest from the viewpoints of a simple device structure and unique thermoelectric/thermospin conversion symmetry. Towards future thermal management applications based on such new functionalities in nano-scaled integrated electronic/spintronic devices, it is crucial to improve active control methods and principles for the spin-caloritronic phenomena. In this work, we report mechanical cooling-heating switching of the anisotropic magneto-Peltier effect, one of the magneto-thermoelectric conversion phenomena, by applying a uniaxial tensile strain.
