AbstractThe magnetocaloric effect (MCE) and the magnetostriction in Ni_49.3Mn_40.4In_10.3 Heusler alloy have been measured ac magnetic fields to 8 T. It is shown that contributions of structural subsystems MCE opposite signs; this case, contribution subsystem dominant. The anomalous temperature dependence during magnetostructural phase transition (PT) explained by competition processes growing austenite nuclei striction them.
