Magnetic susceptibility of multinary diamondlike semiconductors

The magnetic susceptibility of some AIB 2 II CIIIX 4 VI (AI=Cu, Ag; BII=Zn, Cd; CIII=Ga, In; XVI=Se, Te) diamondlike chalcogenides has been measured at RT. Coherently with the form of the relative AICIIIX 2 VI -BIIXVI phase diagrams, their magnetic susceptibility fulfils the sum rule typical of ideal solid solutions. Separate values of the diamagnetic and paramagnetic contributions to total magnetic susceptibility are reported and discussed according to a chemical-bond approach previously described.
