Preparation of Bulk Polycrystalline MnGe_xSb_y (x = 0.5-1.0; y = 1.5-2.2) Doped with Co or Fe

Abstract:

Bulk polycrystalline MnGe_xSb_y materials doped with Co or Fe were prepared and investigated with the aim of obtaining new diluted magnetic semiconductor (DMS) materials. An innovative preparation method was also established. Investigation techniques like X-ray diffraction (XRD), Raman scattering, and scanning electron microscopy (SEM) associated with energy dispersive X-ray analysis (EDX) have been employed to derive the structural properties and the composition of the bulk material.
