Using triaxial magnetic fields to create high susceptibility particle composites

Martin, James E.; Venturini, Eugene L.; Gulley, Gerald L.; Williamson, Jonathan

The use of triaxial magnetic fields to create a variety of isotropic and anisotropic magnetic particle/polymer composites with significantly enhanced magnetic susceptibilities was analyzed. It was shown that a rich variety of structures can be created because both the field amplitudes and frequencies can be varied. It was found that the susceptibility anisotropy of these composites can be controlled over a wide range by judicious adjustment of the relative field amplitudes. The results show that with coherent particle motions, magnetostatic energies that are quite close to the ground state can be achieved.
