摘要：
The magnetic structures of the intermetallic compound La(0.75)Sm(0.25)Mn(2)Si(2) were determined over the temperature region 4.2-500 K by magnetic methods and neutron diffraction. Four different magnetically ordered states are found with critical temperatures of the magnetic phase transitions at T(Sm) = 14 K, T(AF) = 150 K, T(C) = 305 K, and T(N) approximate to 500 K. The peculiarities and possible reasons for the existence of these phase transitions are discussed. (C) 2004 Elsevier B.V. All rights reserved.
