Investigation of Magnetic Susceptibility in an Amorphous Fe43,2Ni23,2Co13,6B20 System
In this paper the temperature dependence of the magnetic susceptibility of an amorphous multicomponent ferromagnetic system was reported. The tests were conducted in the temperature range from 77 to 180 K, and the obtained results were compared with those of relaxed samples of the same composition. The aim of the investigations was to get more information on the structural characteristics of the system, as well as to establish and confirm the existence of early metastable states in the samples frozen at the temperature of liquid nitrogen. For the purpose, a special sensitive method for measuring a.c. magnetic susceptibility was developed, which enabled a simultaneous measurement of the real and the imaginary component of the susceptibility. The obtained results are presented graphically.
