Abstract
Magnetic properties of microcrystalline aligned Dysprosium are reported in order to discuss the perspectives for application of this ferromagnetic material in high magnetic field research apparatus. This technology, based on multistage thermal and mechanical treatment of polycrystalline Dysprosium under high-pressure conditions, provides the alignment of microcrystallites' axes along the [1 1 2 0] crystallographic direction, i.e., along the easiest magnetization axis. Such magnetically aligned material could be saturated completely at a relatively low external magnetic field of 5–7 T, and creates magnetization up to 3.5T, which is close to the highest induction of saturation attainable for any known material in nature. To demonstrate applicability of the material for research appratus design, experiments with the help of a 13.5 T standard superconducting solenoid were performed and additional fields up to 5.1 T were obtained by using magnetically aligned Dy polepieces.
