THE PARTICLE OF HIGHLY DISPERSED MAGNETIC WITH COMPLEX EXCHANGE INTERACTIONS IN AN EXTERNAL MAGNETIC FIELD
Journal Title: Физика аэродисперсных систем - Year 2014, Vol 0, Issue 51
Abstract
The possible types of uniform magnetic ordering in small-sized particle of the uniaxial spin- 1 magnet in an external field have been investigated. The case of the system with complex exchange interactions is considered. The phase diagram of a magnet in the field – temperature coordinates is constructed for certain values of the Hamiltonian parameters. There is a tetracritical point besides a triple point on the phase diagram.
