- Abstract
The thermal variations of magnetizations in a transverse Ising antiferromagnetic bilayer film are examined by the use of the effective field theory with correlations, applying a small magnetic field p. Particular attentions are paid to the systems with a compensation point in the zero applied field ( p = 0.0); that is, what phenomenon can be found in the system, when p takes a finite and small value. From these investigations, we have found a lot of characteristic phenomena. The total magnetization reverses in sign at two temperatures for a case. For another case, it exhibits the first-order transition at a finite temperature, which shows the magnetic phase transition from an incomplete antiferromagnetic state to the ferromagnetic state at a finite temperature.
