Effect of pressure on magnetic properties of a bulk fluoro-metal complex (NH_3OH)_2MF_4 was studied. Magnetization measurements suggest that a ferromagnetic transition at T_{C1} = 47 K is followed by a ferrimagnetic one at T_{C2} = 3 K. Both transition temperatures are pressure dependent with the pressure coefficients dT_{C1}/ dp = - 2.6 K/GPa and dT_{C2}/ dp = 0.26 K/GPa. The opposite sign of the coefficients is an additional indication of a different nature (ferromagnetic/antiferromagnetic) of these two transitions. The effect of pressure on low field magnetization and exchange bias phenomena is small but still visible.
