摘要：
The reflectivity and photoluminescence measurements of quaternary Cd1-x-yZnyMnxTe were performed in magnetic fields B = 0-5 T in Faraday configuration. The magnetisation measurements were also done on the same samples. The exchange integrals were determined and found to be very close to those calculated in linear approximation taking into account the values of exchange integrals for ternary compounds. The bound magnetic polaron effect on the acceptor bound exciton A(0)X was also studied and the destabilisation magnetic field was found. (C) 1999 Elsevier Science B.V. All rights reserved.
