Abstract:
The specific magnetic susceptibility of polycrystalline and powdered samples was measured between 77 °K and 570 °K. This dependence was interpreted in intrinsic range suggesting the susceptibility is given as a sum of contributions of the latticeG and of free carriersL. The temperature dependence of the lattice susceptibility G=G0
+T was checked: G0
=–2·35× ×10–7, =4·5×10–11. The contributionL enabled to check the effective mass of holes mh=0·25m0 suggesting memh.Herrn A. Hrubý gilt mein Dank für die Vorbereitung des polykristallinen Ingots von CdGeAs2.
