Research Abstract

To create artificial easy plane magnets, we have studied magnetic correlations of nano-particulate magnets with random anisotropy and novel technique to control in-plane orientation of easy axes of nanoparticles. Consequently, we found super-speromagnetic ordering between the super-spins and longitudinal, conic, or planar orientations of the easy axes in non-equilibrium steady states in uni-axial alternating magnetic fields.
