【 摘 要 】

Application of external magnetic field over a ferromagnetic material results in change in its global magnetization. Change in global magnetization occurs due to motion of magnetic domain walls to align themselves in the direction of applied magnetic field. The motion of magnetic domain wall generates hysteresis loop consisting of magnetizing curve and de-magnetizing curve. Hysteresis loop is generally characterized by its characteristics such as remnance, coercivity and permeability. In the present study, hysteresis loops were obtained from Ni based sample at different magnetizing field intensity and magnetizing frequency. Hysteresis loops were clubbed together to study the changes in shape owing to variation in magnetizing field strength and magnetizing frequencies. Changes in applied magnetic field strength and magnetizing frequencies affect the process of change in global magnetization process of material. Variation in hysteresis loop shape and its characteristics such as coercivity, remnance and permeability clearly reflects effect of magnetizing field intensity and frequency. A good correlation was obtained between analysis parameters such as magnetizing field intensity and magnetizing frequency with coercivity, permeability and remnance.
