Anomalous Nernst effect dependence on composition in Fe100−XRhX alloys
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 Ner...

| description | 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. |
