Uniaxial magnetic anisotropy of rhombohedral CoC[O.sub.3] crystals at T = 0 K

A method for calculating the contribution of exchange interaction to uniaxial anisotropy with the use of g factors has been worked out using CoC[O.sub.3] crystals as an example. The calculated contribution of dipole-dipole interactions to the anisotropy of CoC[O.sub.3] is 0.93 [cm.sup.-1]. The sum o...

Description
Summary:A method for calculating the contribution of exchange interaction to uniaxial anisotropy with the use of g factors has been worked out using CoC[O.sub.3] crystals as an example. The calculated contribution of dipole-dipole interactions to the anisotropy of CoC[O.sub.3] is 0.93 [cm.sup.-1]. The sum of the contributions to the anisotropy constant of CoC[O.sub.3] with the inclusion of the dipole-dipole interactions is 36.1 [cm.sup.-1].
