Description
Spin Caloritronics is the science and technology devoted to the control of the electron spin with heat in nanoscale structures and devices [1]. It is a subdiscipline of the fields of spintronics, magnetism, and thermoelectrics. A specialized conference series celebrates its 10th edition [2].
Magnetic insulators, especially yttrium iron garnet (YIG), have been crucial material for spin caloritronics since the discovery of the spin Seebeck effect in the YIG|Pt system [3]. YIG is a ferrimagnet with record-high magnetic quality, but a complex crystal structure with a large unit cell. Inelastic neutron scattering experiments [4] interpreted by atomistic simulations [5] are essential for an understanding of spin caloritronic effects.
I this talk I will review the field with emphasis on new developments.
