Abstract
This work presents an investigation of the structure, thermal and magneto-thermal properties of the rare earth metal terbium, which was purified and then underwent severe plastic deformation (SPD). The initial and deformed Tb samples contain nano-sized structural elements, which is confirmed by AFM scans. In high-purity Tb, the magnitude of the magnetocaloric effect (MCE) in the region of the transition to the paramagnetic state exceeds the MCE magnitude shown by Tb samples that have not been purified. It was found that the MCE practically disappears in the deformed sample. The magnetic properties of the samples in the paramagnetic region have been analyzed. It was found that severe plastic deformation makes it possible to obtain a material with new thermal and magneto-thermal properties, due to the transformation of the structure and exchange and magnetocrystalline interactions.
