Magnetoresistive element, method for making the same, and magnetic memory device incorporating the same |
摘要 |
A magnetoresistive element including a free layer having rotatable magnetization, in which information is recorded in the magnetoresistive element by the rotation of the magnetization of the free layer, is provided. The free layer is a laminate that includes at least one ferromagnetic sublayer composed of a ferromagnetic material and at least one low-saturation-magnetization ferromagnetic sublayer having a lower saturation magnetization than that of the ferromagnetic sublayer.
