Abstract :
Single- and multi-layer high saturation magnetization TbFe films with high rectangularity were studied to obtain a film with high remanence. Lamination resulted in greatly improved remanence. No significant variation in Mr and Hc is observed in single-layer and double-layer films, but the remanence ratio for films of three layers or more is almost one and the Hc increases significantly. At three layers Mr becomes 300 G, a very high value compared with single-layer films. Though Ku decreases monotonically with increase in lamination and Hk = 2K¿/Ms decreases too, HC increases resulting in high remanence.
