We have studied the magnetic and magnetocaloric response of MnFe4Si3 to pulsed and static magnetic fields up to 50 T. We determine the adiabatic temperature change ΔTad directly in pulsed fields and compare to the results of magnetization and specific heat measurements in static magnetic fields. The high ability of cycling even in fields μ0H = 50 T confirms the high structural stability of MnFe4Si3 against field changes, an important property for applications. The magnetic response to magnetic fields up to μ0H = 35 T shows that the anisotropy can be overcome by fields of approx. 4 T.
