摘要
Magnetization and Mossbauer-effect measurements were carried out as a function of temperature and external magnetic field of up to 15 T on sigma-Fe100-xCrx (45 less than or equal to x less than or equal to 50) samples. Average magnetic moment per Fe atom, <mu>, and the Curie temperature, T-C, were determined. Both of them were found to linearly decrease with x: the former at the rate of 0.033 mu(B)/at% and the latter at 6.7 K/at%. The results are compared with those from the literature and are discussed in terms of localized and band models. (C) 2003 Elsevier B.V. All rights reserved.
