Twinning in ferromagnetic Heusler Rh2MnSb epitaxial thin films
Original language description
Epitaxially grown full Heusler alloy Rh2MnSb thin films were prepared for the first time using DC magnetron sputtering. The films were deposited on MgO [001] substrates at deposition temperatures of 600◦C, 700◦C, and 800◦C. We report on the structural, morphological, optical, magneto-optical, and magnetic properties of these films, which had a nominal thickness of 200 nm. The film grown at 600◦C was nearly stoichiometric and exhibited the almost perfect L21 ordering typical of Heusler alloys. The single-phase Rh2MnSb film possessed a tetragonal structure with lattice parameters close to the bulk material. X-ray photoelectron spectroscopy revealed the metallic character of the contamination-free film. The tetragonal films displayed discernible regular twinning, where most twin domains oriented with their c-axis perpendicular to the surface, attributed to substrate constraint. Twin formation was investigated using atomic force microscopy, transmission electron microscopy, and X-ray diffraction. Magnetic measurements of the film prepared at 600◦C revealed a Curie temperature (TC) of approximately 220–275 K and a saturation magnetization of around 55 emu/g at 10 K, both values close to the bulk material’s. Magneto-optical Kerr effect measurements confirmed paramagnetic behavior at room temperature. These observed properties highlight the need for further studies of Rh2MnSb’s thin films, focusing on compositional and structural control.
