Magnetic and Electerical Resistivity Behavior of Amorphous Ni Co P Films


, Merc


Magnetic and Electrical Resistivity Study of Electroless Amorphous Ternary System (Ni-Co-P) show a qualitative dependence of crystalline phases formed during transformation on the annealing temperature and composition. Electrical Resistivity values increases with increase in cobalt content and samples with higher resistivity show lower temperature coefficients. The Initial increase in magnetization is due to separation of crystalline magnetic phases (a-Cobalt and f.c.c. Nickel), and tends to decrease by formation of equilibrium phases at higher temperature.
