Abstract

In the present work, the phase constitution and magnetic properties of the LaFe11.14Co0.66Si1.2-xGax (where x = 0.1, 0.2, 0.3) alloys, were investigated. It was revealed that increase of Ga content in the alloy composition causes the rise of lattice parameter of the La(Fe,Si)13-type phase, which causes increase of the Curie temperature. However, the increase of Ga addition leads to decrease of magnetocaloric eect.
