摘要
The temperature dependence of the magnetization in nanocrystalline Cu0.5Fe0.5-xCox (x = 0.0, 0.1, 0.2, 0.4) powders, manufactured by mechanical alloying in a high-energy ball mill, has been studied by means of magnetometry and ferromagnetic resonance experiments. The Curie temperatures of the solid solutions increase with Co content. The spin wave stiffness constant and the range of the exchange interaction increase with increasing Co content, indicating the hardening of the exchange interaction by Co substitution.
