Abstract

Metallic Glass $Fe_{81}Si_{3.5}B_{13.5}C_2$ was annealed by furnace, low current and pulse annealing methods. Coercivity Hc measurements were taken for all techniques and their results compared. Advantages and limitations of the methods are discussed. Pulse annealing method, which gives very short annealing time and lowest Coercivity $H_c$ value is described in detail. Electrical resistivity of $Fe_{81}Si_{3.5}B_{13.5}C_2$ was taken by four probe method in order to determine the Curie temperature $T_c$, and Crystallization temperature $T_x$.
