Abstract

Magnetic properties of the Lu2Fe17 single crystal and its hydride Lu2Fe17H1.5 have been studied by means of magnetization and magnetostriction measurements. An unusual magnetic behavior with two magnetic phase transitions has been observed in the host compound. It was found that hydrogenation leads to suppression of antiferromagnetism and induction of the ferromagnetic state with a high Curie temperature (T C = 393 K). The hydrogenation exerts a significant influence on magnetoelastic properties of the Lu2Fe17 single crystal: a thermal expansion along the c-axis becomes positive, magnetostrictive deformations decrease.
