Аннотация
We present a new technique for experimental study of kinetics of phase transitions (PTs) and direct measurement of the magnetocaloric effect (MCE) in pulsed magnetic fields by using the fast response temperature probe with infrared fiber optical (IRFO) sensor. As demonstration of the new technique, the results are presented of MCE measurements for Gd near Curie point:Delta T-ad = 21.3 K under pulsed magnetic field mu H-0 = 12.7 T; and inverse MCE for Fe48Rh52 sample at initial temperature 305.1 K: Delta T-ad = - 4.5 K under pulsed magnetic field mu H-0 = 8.5 T. Also, the energy losses on magnetization near the 1st order PT were calculated from the results of direct measurements of magnetization versus time for Fe48Rh52 sample: W - 45 J/kg.
