摘要：

The results of direct measurements of the magnetic field induced entropy change in the Ni2.19Mn0.81Ga alloy are presented. It is shown that the largest entropy change in the magnetic field 2.6 T is equal to 11 J/kgK. The experimental data are compared with the theoretical results, obtained with the help of the statistical and molecular field theory.
