Effect of a magnetic field on the thermal expansion of Ni$_{2.08}$Mn$_{0.96}$Ga$_{0.96}$ alloys

The effect of a magnetic field on the temperature dependence of thermal expansion of Ni$_{2.08}$Mn$_{0.96}$Ga$_{0.96}$ alloy in the range of structural-phase transformation is investigated. It is found that, when the sample is cooled in a magnetic field with an intensity of 110 kA/m, it shortens by 0.21% more strongly than upon cooling in the absence of the magnetic field. The additional shortening of the sample under the action of the magnetic field depends on the intensity of the magnetic field applied to the sample.
