Effect of a flash Cr interlayer on properties of CoCrTa/Cr media

抄録

In a double layered CoCrTa film separated by a thin flash Cr interlayer, coercivity and coercivity squareness drastically change with increasing the Cr interlayer thickness. There was some coercivity increase in double layered films compared to single layer when the flash Cr interlayer thickness were around 8 to 10A and coercivity decreased with further increase of the Cr interlayer thickness up to 50A. A micromagnetic simulationt technique was employed to understand the coerdvity changes as a function of the interlayer thickness. The simulation results showed fluctuation of coercivity at a thin interlayer thickness range and coercivity becomes a constant value with further increase of the interlayer thickness. These will be discussed.
