“…Moreover, several sets of the molecular-field coefficients have been determined, and, the temperature-dependence of the molecular-field coefficients has been pointed out [17]. However, it is found that the recent experimental phenomena on magnetic properties in DyIG, especially under high magnetic fields and low temperatures, have not been theoretically explained [18,19]. So, now, the above threesublattice model is applied to interpret the magnetic properties of DyIG in high magnetic fields.…”
