Abstract

We investigate the anomalous Nernst effect in epitaxial SrRuO₃ thin films grown on c-cut Al₂O₃ substrates, and in a polycrystalline SrRuO₃ slab. Through comprehensive measurements of the transverse thermoelectric response as a function of temperature and magnetic field, we observe a pronounced Nernst signal near T_c in the (111) oriented SrRuO₃ thin films. The strong temperature and nontrivial field dependence underscore the pivotal role of the magnetic anisotropy in tuning the Berry curvature and, consequently, the anomalous Nernst effect in SrRuO₃.
