Low-field magnetic properties of (Zn1-xMnx)3As2

Abstract Mechanism of generation of complex centres with a large magnetic moment and many spin degrees of freedom, called clusters of polarization, is proposed. The idea is based on remanent disorder in structure of alloys. Conditions of freezing-in of the system of interacting clusters of polarization in (Zn 1- x Mn x ) 3 As 2 are studied.
