摘要：
The magnetisation curve and the critical temperature of the square Ising lattice with a fluctuating exchange integral has been investigated using the Matsudaira method. Particular attention has been drawn to the reentrant ferromagnetism phenomenon and it has been shown that it strongly depends on the accuracy of calculations with a tendency to disappear when the accuracy is improved.
