Magnetic Susceptibilities of Cr and Cr-Fe Alloy

The magnetic susceptibilities of Cr and Cr-Fe are investigated by the use of the band picture for 3d electrons. The temperature increase of the magnetic susceptibility of Cr is attributed to a minimum of the electron state density. For the shape of the band of Cr two models are adopted, and the calculated susceptibilities are compared with the observed ones. According to this comparison the shape of the band of Cr is discussed, and the result on its shape is compared with that calculated from the specific heat measurement at low temperatures by Cheng et al.
