Temperature Dependence of Magnetization of Lu_2Fe_(17) Compound in Different Structural states

摘要

In the present work we report our studies of temperature dependence of magnetization and structure analysis of Lu_2Fe_(17) samples. The samples revealed various, coarse grained, submicrocrystalline, and nanocrystalline microstructures. It was found that in nanocrystalline state the Lu_2Fe_(17) compound has a higher coercive force, retains phase composition and does not disintegrate during heating. The curves of the temperature dependence of magnetization were recorded for all investigated structural states and indicated that nanocrysatlline sample had a higher Curie point.
