Abstract:

In this work, we prepared SmCo5 thin films with (000l) texture exhibiting perpendicular anisotropy in a wide range of SmxCo100−x compositions (x = 13.2∼37.0) on Cu/Ta underlayers. At a composition of Sm16.7Co83.3(SmCo5), the SmCo5 film exhibits a maximum perpendicular coercivity of 18.2 kOe, which is attributed to a good crystallinity and an excellent (000l) texture. The SmCo5 (000l) peaks are shifted to smaller angles compared to the standard powder sample which indicates the formation of a SmCoCu alloy through Cu diffusion. The EDX result for this sample gives a composition of SmCo3Cu2.1 which confirms Cu diffusion into the SmCo5 layer. TEM image shows that SmCo5 film is well crystallized with a grain size of 50 nm.
