The influence of rapid recurrent thermal annealing on magnetic properties of CoFe-O thin film

The variation of magnetic properties with a new rapid recurrent thermal annealing (RRTA) were studied in high moment thin film (Co 0.35Fe0.65)99O1. After the rapid recurrent thermal annealing at 450°C for several periods of times, the coercivity as-deposited this thin film decreased from 105 to 3 Oe, and their resistivity was decreased to 70 percent. It is found that the method is more effective than other methods to improve the magnetic and electrical properties of (Co0.35Fe0.65)99O1 thin films.
