Abstract
Magnetic and structural properties of amorphous Co80-xCrxSi6B14, x=0, 2, 4, 6 and 8 at. , alloys were investigated. Temperature dependences of saturation magnetizations and relative initial susceptibilities were compared with the temperature dependences of heat flow obtained by DSC technique. Two crystallization temperatures were obtained in the temperature range 300-870 K. First crystallization leads to the formation of magnetically harder ferromagnetic material. Second crystallization additionally increases magnetization of the samples with 0 and 2 at. Cr and decreases it for higher Cr content. Concentration dependences of saturation magnetization, Curie as well as crystallization temperatures are reported. Increase of Cr contents decreases coercive fields of alloys. The influence of the under-critical annealing on the coercivity is discussed.
