Due to the mutual antiparallel arrangement of Gd and 3d sublattices and the negligible pressure effect on localized Gd magnetic moment,the observed increase of Ms with pressure (dMS.5 K/dp = +0.007 μB kbar-1) can be attributed to the pressure induced decrease of 3d magnetic moments, predominately to the decrease of Fe moment, dmFe/dp = -2.8.10-3 μB/at. kbar. The pressure induced increase of MS is also responsible for the remarkable increase of TComp under pressure (dTComp/dp = +0:90 K/kbar). This opens the field to tunablibilty of the TComp.
