| Description: | We consider a system of randomly distributed magnetic atoms and describe the exchange interaction in the Ising model with a hydrogen-like dependence of the exchange energy on distance. The density of states for such system was calculated using an advanced numerical algorithm. Also the density of states was calculated an analytically. It is shown that knowing the density of states, one can calculate the dependence of the magnetic susceptibility of the system on temperature and magnetic field. Мы рассматриваем систему случайно распределенных магнитных атомов в модели Изинга с водородоподобной зависимостью обменной энергии от расстояния. Плотность состояний для такой системы посчитана численно и аналитически. Показано, что, зная плотность состояний, несложно рассчитать зависимость магнитной восприимчивости системы от температуры и магнитного поля. |
