Summary
The temperature dependence of the magnetic susceptibility ((300÷78) K) of some polycrystalline I–III–VI2 semiconductors has been determined. Some of the materials show a temperature-independent diagmagnetic behaviour. CuInS2 and CuInSe2 show changes in the diamagnetic susceptibility assumed to be due to the presence of a temperature-dependent paramagnetic term from noninteracting trapped carriers.
Riassunto
La dipendenza dalla temperatura della suscettibilità magnetica ((300÷78) K) di alcuni semiconduttori policristallini I–III–VI2 è stata determinata. Alcuni dei materiali mostrano un comportamento diamagnetico indipendente dalla temperatura. CuInS2 e CuInSe2 mostrano cambiamenti nella suscettibilità diamagnetica che si suppone siano dovuti ala presenza di un termine paramagnetico dipendente dalla temperatura da portatori intrappolati non interagenti.
Резюме
Псследуытся температурная зависимость магнитной восприимчивости ((300÷78) K) некоторых поликристаллических полупроводников I–III–VI2. Некоторые соединения обнаруживаут диамагнитное поведение, не зависящее от температуры. CuInS2 и CuInSe2 обнаруживают изменение диамагнитной восприимчивости, что, по-видимому, обусловлено оналичием зависящего от температуры парамагнитного члена, связанного с невзаикодействующими захваченными носителями.
