|Title:||Induced Staggered Magnetic Fields In Antiferromagnets: The G-factor Mechanism|
|Abstract:||We have calculated the phase diagrams for an Ising antiferromagnet in an external field when the transverse g factors of the two sublattices are unequal. We find that the induced staggered magnetic field allows the external field to couple to the antiferromagnetic order parameter, preventing the occurrence of second-order phase transitions except at isolated critical points. Quantitative results based on mean-field theory are presented. © 1977 The American Physical Society.|
