abstract = {The influence of hydrostatic high pressure on the crystal
structures and magnetic properties of magnetocaloric Mn5Si3
and MnFe4Si3 was studied with temperature dependent
synchrotron powder diffraction, neutron single-crystal
diffraction and magnetization measurements. Mn5Si3 shows no
indication for any pressure-induced structural phase
transition up to 24.2 GPa at room temperature. MnFe4Si3
exhibits no clear indication for any phase transition at
high temperatures (296 K–373 K) and high pressures.
Anomalies in the lattice parameter at low temperatures
indicate a structural response to magnetic ordering. The
gradient of decreasing magnetic transition temperature with
increasing pressure is dT C/dP ≈ −15 K GPa−1. The
transition temperature in MnFe4Si3 can be tuned by pressure
in the temperature range relevant for applications, while
pressure has hardly any detrimental influence on other key
features relevant to magnetocaloric applications (the width
of hysteresis, saturation magnetization, magnetocrystalline
anisotropy).},
