Research Abstract

The magnetic properties of nanoparticles depend on their size. The studies of the size effects have been conducted mainly via chemical approaches, which yields discontinuous change in structural parameters. We have performed the hydrostatic pressure experiment for prototypes of magnetic nanoparticles by pursuing the magnetic blocking temperature, coercive field, magnetic moment per one particle, and structural parameters, in order to conduct the systematic study from the physical viewpoint. However, the particle shape has never been considered as a structural factor to explain the magnetic properties. Thus, in order to make the influence of particle shape prominent, we have developed the physical method of inducing anisotropic strain to nanoparticles, and elucidated how the change in the particle shape as well as those in structural parameters of the unit size level give important influence to the magnetic properties.
