| Abstract: | Ginzburg-Landau theory is used to investigate states in which both superconductivity and ferromagnetism exist simultaneously in certain rare-earth ternary compounds. The "spontaneous vortex state" of Kuper, Revzen and Ron is reexamined and extended to include magnetic oscillations within each vortez cell and the existence of antiferromagnetically aligned vortices. The "linearly polarized state" of Greenside, Blount and Varma is reinvestigated in what appears to be a more physically acceptable range of parameters that are used in the Ginzburg-Landau free energy function. The "square antiferromagnetic vortex lattice state" proposed by Hu and Ham is investigated here for the first time, energetically compared to the states proposed by Kuper, et. Al. and Greenside, et al., and used to model the observed coexistence state observed in ErRhB.... |
