The longitudinal spin Seebeck effect (LSSE) consists in the generation of a spin current parallel to a temperature gradient applied across the thickness of a bilayer made of a ferromagnetic insulator (FMI), such as yttrium iron garnet (YIG), and a me

In this work, we produced Y3Fe5O12 textured films, with thicknesses between 50 nm and 500 nm, onto (1 0 0) Gd3Ga5O12 by magnetron sputtering and post annealing, and investigated the first and second order surface and cubic anisotropy constants using
