Influence of Milling upon the Magnetic Properties of the …

The influence of milling upon some magnetic properties of the intermetallic compound MnAlGe has been studied. The Curie temperature of the material seems to be independent of particle size and is constant at 245 C. The saturation magnetization σ s, which is 55 erg/Oe·g in the annealed state, decreases as the grinding time increases. ...
