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 ΔT_ad 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.
