Magnetocaloric Effects of LaFe_(12.2-x)Co_(0.9)Si_xB_(0.25)
Three groups of LaFe12.2-xCo0.9SixB0.25(x=1.1,1.3,1.5) alloys were prepared in a high-frequency floating furnace,and the change of adiabatic temperature was tested.The results show that,changing the content of Si in the alloy,the Cure temperature can be adjusted to a suitable figure and the better magnetocaloric effects are kept.The adiabatic temperature of the alloy is maximum as the content of Si is 1.1%.
