Behaviour of a three-dimensional uniaxial magnet near the critical point in an external field
The behaviour of a three-dimensional magnet with a one-component order parameter near the critical point in a homogeneous external field is investigated. The calculations are performed in the case when the field and temperature are dependent and related by some expression (the system tends to th...

| description |
The behaviour of a three-dimensional magnet with a one-component order
parameter near the critical point in a homogeneous external field is investigated.
The calculations are performed in the case when the field and temperature
are dependent and related by some expression (the system tends
to the critical point along some trajectory). The high- and low-temperature
regions in the vicinity of Tc ( Tc is the phase transition temperature in the
absence of an external field) are considered. It is shown that in the weak
fields the system behaviour is described in general by the temperature variable,
but in the case of the strong fields the role of the temperature variable
is not dominant. The corresponding expressions for the free energy, susceptibility
and other characteristics of the system are obtained for each of
these regions. |
