 The exchange-coupled, co-slash-n-i, n-slash-tb-phane nanomagnetic films can display strong perpendicular magnetic anisotropy, PMA, which depends on the tb-phane component ratio, tb-phane layer thickness and the repetition number n of, co-slash-n-i, n-multi-layer. The perpendicular spin valves in the nano-thickness scale, consisting of a, co-slash-n-i, 3-free in a, co-slash-n-i, 5-slash-tb-phane reference multilayer, show high giant magneto-resistance, GM, signal of 6.5% and a large switching field difference over 3-co. However, unexpected slanting of the free-layer magnetization, accompanied by a reduced GMR ratio, was found to be caused by the presence of a thick-phay-rich or even a thin but tb-rich tb-phay layer. We attribute this phenomenon to the large magnetostriction effect of tb-phay, which probably induces strong stress acting on the free-layer and hence reduces its interfacial PMA.
