In this work, we prepared high-coercivity SmCo<sub>5</sub> thin films with in-plane or out-of-plane anisotropy. Our
research work focused on the induction of highly textured SmCo<sub>5</sub> thin films using suitable underlayers. A Cr underlayer
was used for the fabrication of SmCo<sub>5</sub> with in-plane anisotropy. The nanocrystalline SmCo5 thin films with a (1120)
texture exhibited high in-plane intrinsic coercivity up to 18.5 kOe. On the other hand, with a Cu underlayer, highly
(0001) textured SmCo<sub>5</sub> thin films showed large perpendicular anisotropy and high coercivity up to 20 kOe. Our research
work showed that a very thin seedlayer (4nm) of Ta can improve the crystallinity and texture of the (111) Cu underlayer.
The high quality Cu underlayer can result in high magnetic performance of SmCo<sub>5</sub> thin films.
