The structural, magnetic and magnetocaloric properties of MnCrNiGeSi high-entropy alloy
The structural, magnetic and magnetocaloric properties of Mn 20 Cr 14 Ni 33 Ge 25 Si 8 and Mn 24 Cr 10 Ni 33 Ge 25 Si 8 high entropy alloys (HEAs) were investigated. The HEAs were prepared by arc melting method. The structural analysis indicates that the structure of HEAs is orthorhombic with Pnma s...
