摘要：

The magnetization of dysprosium (Dy) in its different structures (from a nanocrystalline one to a coarse grained structure) is investigated. In the nanocrystalline state Dy is ferromagnetic up to a temperature 160 K and no antiferromagnetism is detected at any temperature when Dy is in an intermediate structural state, coexistence of the ferro- and antiferromagnetic orders is observed in the temperature range from 110 to 160 K. Finally, magnetic properties of coarse-grained Dy coincide with those reported in literature for the bulk. (C) 1996 American Institute of Physics.
