With recent progress of nanotechnology for spin-electronic devices, a rich potential for nanomagnets has attracted considerable attention. Some fundamental issues, however, are still open to question. This study throws a new light on the issues by using the techniques: preparation techniques for uniform nanomagnets and techniques for estimation of equilibrium states.Subjects--Topical Terms:

520 $a With recent progress of nanotechnology for spin-electronic devices, a rich potential for nanomagnets has attracted considerable attention. Some fundamental issues, however, are still open to question. This study throws a new light on the issues by using the techniques: preparation techniques for uniform nanomagnets and techniques for estimation of equilibrium states.
520 $a The results show that conventional models for classical phenomena of individual nanomagnets should be renewed in some respects. In addition, it is shown that existence of macroscopic quantum phenomena is doubtful in the Kelvin regime, even if magnetization of the individual nanomagnet is considerably small. On the other hand, we can find that assembled nanomagnets show cooperative phenomena: spin glasslike order in randomly assembled nanomagnets and some phase transitions in dipolar-coupled nanomagnets with sufficient mobility. Some references are appended for English-speaking readers.
