Abstract
The fractal structure of the phase equilibrium curve of a system of two interacting magnetic moments in the presence of a uniform low-frequency bias magnetic field is found by numerical methods. It is established that as frequency increases, the phase equilibrium curve becomes smooth. For that case an exact solution of the dynamical equations is found which gives a good description of the numerical results.
