    • A magnetoresistive read head includes a spin valve having at least one free layer spaced apart from at least one pinned layer by a spacer. The free layer includes a cobalt compound as a thin film including at least one of Co—X, CoFe—X and CoNi—X, where X is an element from the lanthanoid family (a 4-f element). The content of Co is higher than 80 percent, and the content of the lanthanoid element is less than 10 percent. The film may comprise the entire free layer, or be positioned adjacent to one or more conventional free layer films. The pinned layer is a conventional single layer, or a synthetic multi-layered structure having a spacer between sub-layers. Because the spin valve structure has a high exchange stiffness and damping factor, spin transfer effect is reduced and a high-speed dynamic response is provided.
    • 磁阻读取头包括具有至少一个自由层的自旋阀,所述至少一个自由层通过间隔件与至少一个钉扎层隔开。 自由层包括钴化合物作为薄膜,其包括Co-X,CoFe-X和CoNi-X中的至少一种,其中X是来自镧系元素族的元素(4-f元素)。 Co含量高于80%,镧系元素含量低于10%。 膜可以包括整个自由层,或者被定位成与一个或多个常规的自由层膜相邻。 被钉扎层是常规单层,或在子层之间具有间隔物的合成多层结构。 因为自旋阀结构具有较高的交换刚度和阻尼因子,所以自旋转移效应降低,并提供高速动态响应。
