    Influence of substrate type and magnetic anisotropy on the spin Seebeck effect in ZnFe2O4 thin films

    The longitudinal spin Seebeck effect (LSSE) has been investigated in ZnFe2O4 (ZFO) thin films on different substrates, such as Si (111), MgO (100), and SrTiO3 (100). The LSSE voltage signal exhibited a linear dep...
