In recent years, magnetic refrigeration has attracted much attention as an energy-saving and environmentally friendly technology. Studies have been devoted to investigate the room-temperature magnetic refrigeration materials from rare-earth magnetic materials, such as Gd5Ge2Si [3 and La(Fe, Si)-based alloys, to transition-metal magnetic materials, like MnFeP1−xAsx alloys. Most recently, Wang et al...
In this study, the magnetic properties of Mn1-xCoxGe compounds such as dc magnetization, Curie temperature and saturation magnetization are presented. An anomalous comparatively high magnetic moment is observed in MnFe0.2Co0.8Ge. The magnetocaloric effect (MCE) such as magnetic-entropy change was investigated using magnetization.
The structural and magnetic properties of MnFe1-xCoxGe compounds with x=0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.85,0.9, and 1.0 were investigated by means of X-ray diffraction (XRD) and magnetization measurements. XRD shows that the MnFe1-xCoxGe compounds crystallize in the hexagonal Ni2In-type crystal structure for xles0.8 and in the orthorhombic NiTiSi-type structure for x>0.8. The magnetization...
