Abstract
The TbFeCo films were prepared at argon gas pressure PAr of 0.8 and 3.6 mTorr by using the facing targets sputtering (FTS) apparatus. The films showed the polar Kerr rotation angle θk as large as 0.43° at a wavelength of 830 nm. In polar Kerr hysteresis loops, the films with large θk showed the rectangular loops in which the gradient of magnetization at an applied field of coercivity was extremely large. Moreover, the films deposited at PAr of 0.8 mTorr showed the strong wavelength dependence of θk compared with the ones deposited at PAr of 3.6 mTorr.
