Structural, electronic and magnetic properties of the Fe8−Mn Rh8 compound: A density functional study

Controlling the Metamagnetic Phase Transition in FeRh/MnRh Superlattices and Thin-Film Fe50-xMnxRh50 Alloys

“…FeRh has been intensely investigated in the last few decades as a test bed to explore both fundamental and practical aspects of first-order phase transitions and nanoscale phase coexistence. In contrast, contemporary experimental studies on MnRh are relatively scarce with metamagnetic thin films being only reported recently. , First-principles calculations confirmed the stability of AF and FM ordering in this material, pointing to a substantial strain dependence of the magnetic anisotropy energy in the AF phase. − Remarkably, Fe–Mn–Rh alloy systems have also been theoretically considered very recently, predicting a tetragonally distorted cubic lattice in their FM phase …”

“…50−52 Remarkably, Fe−Mn− Rh alloy systems have also been theoretically considered very recently, predicting a tetragonally distorted cubic lattice in their FM phase. 53 In this work, we fabricate epitaxial FeRh/MnRh superlattices and Fe 50-x Mn x Rh 50 alloy films with tunable metamagnetic properties via cosputtering. The structural characterization demonstrates the attainment of highly ordered and tetragonally distorted epitaxial films and multilayers on MgO(001) substrates.…”
