Abstract

Behaviours of the parameters ST and SH as well as irreversible "susceptibilities" kirr and dirr, which characterize the magnetic aftereffect of strain, are studied for the (Fe0.965Ni0.035)0.49Rh0.51 alloy in the region of temperature and magnetic field induced first order magnetostructural phase transitions. The universal constants kT/r and kT/q (which are independent of the shape of specimen and kinds of dependences of strain versus temperature and field) as well as activation volumes ι'T and ι'H are estimated from the experimental data. Inapplicability of the Kittel's theory for the description of the investigated phase transition in FeRh based alloys is discussed. The results obtained in the work are compared with known ones for high-coercivity materials.
