Measurements with the field parallel to the moment direction confirm the presence of two first-order transitions above 35 Tesla, to M/Msat = 1/2 and M/Msat = 1, respectively, at 4 K. The measurements are in contradiction with published estimates for the magnetic exchange parameters, but the contradiction can be resolved by allowing for anisotropic exchange parameters in the Hamiltonian. The magnetisation with the field perpendicular to the moment direction is anisotropic, with no transitions observed for fields along the a axis while a cascade of first-order transitions is observed for fields above 50 Tesla along the b axis, the latter case also showing a strong degradation of the sample after repeated pulses. The results indicate a strong magneto-lattice coupling in FePS3. Temperature-dependent measurements hint at a possible tricritical point. %G English %2 https://cnrs.hal.science/hal-03029896/document %2 https://cnrs.hal.science/hal-03029896/file/FePS3_HiField_PRB_2.pdf %L hal-03029896 %U https://cnrs.hal.science/hal-03029896 %~ CEA %~ UGA %~ CNRS %~ INPG %~ NEEL %~ NEEL-MAGSUP %~ IRIG %~ CEA-GRE %~ UGA-EPE %~ PHELIQS %~ TEST3-HALCNRS
