MnGa films of few nanometer thickness with tetragonal zinc-blende (TZB) structure were grown by molecular beam epitaxy on GaAs(111) substrates. These ultrathin films have high magnetization at room temperature with magnetic moment as high as 3.2 μ B

We investigate the chemical reactivity of ultra-thin films of Mn on As-terminated (111) GaAs surface kept at ultra-high vacuum conditions in the temperature interval ranging from room temperature to 400 °C. The experiments were performed using a cus

MnGa alloys with compositions in the range of 52 to 60 at. % Mn were grown by molecular beam epitaxy (MBE) on GaAs(111)B substrates. High quality epilayers were obtained at growth temperatures between 25 and 250 °C. Epilayers are stabilized by post-

In this work we describe the fabrication of FeCo alloy (less than 10 at% Co) thin films from aqueous ammonium sulfate solutions onto n-type Si(111) substrates using potentiostatic electrodeposition at room temperature. The incorporation of Co into th

Compact rolled-up nanomembranes of high quality (111)-oriented Co/Pt multilayers with perpendicular magnetic anisotropy are realized by combining strain engineering with top-down preparation methods. Magnetic force microscopy analyses were performed

We report on high quality MnGa epilayers directly grown on GaAs(111)-(1 × 1) reconstructed surface. MnGa layers are characterized by the stacking of (111) planes of tetragonal zinc-blende structure, which are rotated by 11° with respect to the unde
