2. 1. Magnetism of Semiconductors and Metallic Multilayers

   Author : Victor Stanciu; Per Nordblad; Peter Svedlindh; Poul Erik Lindelof; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Magnetic order; Curie temperature; magnetic anisotropy; diluted magnetic III-V semiconductors; metallic magnetic multilayers; interlayer exchange coupling; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : Magnetic properties of diluted magnetic semiconductors and magnetic metallic multilayers are investigated by SQUID magnetometry. By doping GaAs with magnetic Mn2+ ions under well defined growth conditions, one obtains a diluted magnetic semiconductor, (Ga,Mn)As, in which the randomly-distributed magnetic ions act as acceptor centers.
