Abstract :
The epitaxial growth of the SmCo5 phase and the possibility for obtaining a homogenous film with improved magnetic properties compared to the epitaxial Sm2Co7 films were explored. Pulsed laser deposition (Kr-F excimer laser) from elemental targets was used to obtain these films on single crystal MgO(100) substrates with Cr buffers. Film thickness and compositions were determined by voltage-dependent X-ray chemical analysis measurements and first information about the phase formation is derived from X-ray diffraction. Pole figure measurements using CaRIne crystallography reveal four discreet and sharp poles, which indicate complete crystallization in the film. Results also confirm phase purity, and a very strong magnetic in-plane texture and high coercivity.
