Abstract

We studied the anomalous Nernst effect (ANE) in CsCl-type Fe100-XRhX (X = 45, 48, 50, 52, 54, 60) with a thickness of 50 nm deposited on a thermally oxidized Si substrate. Samples with X < 48 certainly have a ferromagnetic phase, exhibiting the ANE. The composition dependence of the anomalous Nernst coefficient Syx agreed with the transverse thermoelectric conductivity αyx. |Syx| and |αyx| were maximized at X = 48, which has a ferromagnetic state close to the phase transition state. The maximization of |αyx| at X = 48 can be explained using band structure-based calculations, where |αyx| rapidly increases near the phase transition.
