Description
The Rashba-type spin orbit coupling found at the interface of two dimensional electron gases (2DEGs) is of great interest for spintronic applications. Here, we uncover the nature of spin transport from a 2DEG to magnetic metal via second harmonic Hall measurements, spin-torque ferromagnetic resonance, and temperature-dependent ferromagnetic resonance (FMR). While FMR indicates enhanced spin current absorption by the 2DEG, second harmonic Hall measurements reveal a large thermoelectric signal suggesting a strong in-plane thermal gradient generated by passing current through the LaTiO$_3$.
