Abstract

We investigate the anomalous Nernst effect in epitaxial SrRuO $_3$ thin films grown on c-cut Al $_2$ O $_3$ substrates, and in a polycrystalline SrRuO $_3$ 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 SrRuO $_3$ 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 SrRuO $_3$ .
