reference to Prior Experiments Description
enlarge change of magnetization when encountering small temperature change -> large magnetocaloric effect -> transfer more thermal energy from heating to cooling -> cooling application like refrigerator
first-order magnetic transition near room-temperature
from the substitution of Co for Ni you can expect higher magnetization
A small amount of Al substitution for Ge can lower the structural transition, resulting in a coupled first-order magnetostructural transition has been realized in MnNi1-xCoxGe0.97Al0.03
