Ferrimagnetism in a transverse Ising antiferromagnet

• The phase diagrams and magnetizations of a transverse Ising antiferromagnet consisting of two A and B layers are examined by the uses of the EFT and the MFA.
• Ferrimagnetic behaviors have been found for the total magnetization.

The phase diagrams and temperature dependences of total magnetization mT in a transverse Ising antiferromagnet consisting of alternating two (A and B) layers are studied by the uses of the effective-field theory with correlations and the mean-field-theory. A lot of characteristic phenomena, namely ferrimagnetic behaviors, have been found in the mT, when the crystallographically equivalent conditions between the A and B layers are broken. The appearance of a compensation point has been found below its transition temperature.
