Abstract:
Magnetocaloric effect (MCE) in pulsed magnetic fields up to 50 T was directly studied in alloy Fe$_{49}$Rh$_{51}$. An inverse MCE $\Delta T\approx$ - 8 K is observed at different initial temperatures around the metamagnetic phase transition upon field rising to 20 T; further growth of the field to 50 T leads to a decrease in the absolute adiabatic temperature change by nearly 1 K, which is due to the direct MCE and proves that the whole sample undergoes a transition into the ferromagnetic phase. Upon the field decrease, the maximal absolute value of the adiabatic temperature change of $|\Delta T|$ = 9.8 K was revealed at 6 T when the initial temperature is 310 K.
