摘要：
Low temperature magnetization in polycrystalline Gd0.7Ca0.3Mn1-x M (x) O-3 (M=Cr, Ga, Ru; x=0, 0.2) has been investigated. The samples were prepared via the conventional solid state reaction method. For all the samples, the paramagnetic to ferrimagnetic (PM-FiM) transition temperature (say T (max)) can be well defined from the temperature dependent ac susceptibility data. The negative magnetization suppresses due to 20 % Cr or Ga doping at the Mn site. On the other hand, below the compensation temperature (T (comp)), the nature of the Ru doping sample is almost similar to that of undoped Gd0.7Ca0.3MnO3. The nonmagnetic Ga doping drastically reduces magnetization and T (max) shifts to a lower temperature. However, Ru and Cr doping increase the value of T (max). The network of canted Mn3+/Mn4+ moments changes with the substitution of Cr, Ga, and Ru at the Mn site giving rise to the variation of the internal magnetic moment. Thus, the antiparallel coupling of the Gd moments with Mn/M changes and affects the low temperature magnetization reversal properties.
