The langasite-type crystals with 3d ions are considered as a class of multiferroics in which ferroelectricity can be induced by the magnetic ordering. In this paper, the high-pressure magnetic states of the langasite-type powdered sample Ba3TaFe3Si2O14 have been investigated in a diamond anvil cell by the nuclear forward scattering of synchrotron radiation technique at different temperatures in hydrostatic conditions. In the pressure range of 0 < P < 19.5 GPa, an increase of the Neel temperature T-N from 27 to 41 K was observed in the antiferromagnetic phase of the material. At pressures similar to 19.5 GPa, a transition to another magnetic phase with huge increase in the Neel temperature to similar to 120 K was found. We attribute this change to the structural transition at similar to 19.5 GPa which is evidenced by a drastic change of Raman spectra at this pressure. A tentative magnetic P-T phase diagram of Ba3TaFe3Si2O14 is proposed. (C) 2013 AIP Publishing LLC.
