“…Many studies on the preparation of the ordered FeRh thin films have been made, since it has been pointed out by J.M. Lommel that thin films of FeRh exhibit a broad, incomplete magnetic transition and large thermal hysteresis in contrast to the clear first-order transition in a bulk sample [2,3].In this paper, a method for growing FeRh thin films on fused silica (SiO 2 -glass) substrates with a good ð0 0 1Þ texture is presented. In addition, epitaxially grown FeRhð0 0 1Þ films on MgOð0 0 1Þ substrates are prepared and the magnetic, and crystalline properties of the films grown on two different substrates are compared.…”

“…20,21) In this study, we focused on FeRh alloy, which has a magnetic phase transition that depends on the temperature and composition. [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] It has been reported that FeRh alloys undergo a magnetic phase transition from antiferromagnetic (AFM) to ferromagnetic (FM) with a change in the band structure when the FeRh alloy has a CsCl-type ordered structure. 37,38) Therefore, FeRh is a suitable material for investigating the relationship between yx a and the band structure by continuously changing the composition of FeRh.…”

We studied the anomalous Nernst effect in CsCl-type Fe100-X Rh X (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 anomalous Nernst effect. The composition dependence of the anomalous Nernst coefficient S yx agreed with the transverse thermoelectric conductivity α yx. |S yx | and |α yx | were maximized at X = 48, which has a ferromagnetic state close to the phase transition state. The maximization of |α yx | at X = 48 can be explained using band structure-based calculations , where |α yx | rapidly increases near the phase transition.

“…FePd and FeRh alloys raised early interest as it has been shown that Pd and Rh become magnetically active with appreciable induced polarization such as in the presence of Fe impurities [4] or in Pd/Fe and Fe/Rh systems [5], [6]. Fe 0:5 Pd 0:5 as bulk or film [7] and FeRh thin films [8] has been extensively studied in recent years. A relevant point of general agreement is the strong Fe-Pd(Rh) ferromagnetic coupling.…”
