Anotace	The study of the structural and magnetic properties of YFe2D4.2 under high pressure has been performed by combining energy dispersive x-ray diffraction at room temperature up to 5.5 GPa, neutron diffraction studies at low temperature up to 2.5 GPa, and magnetization measurements up to 1 GPa. The monoclinic structure of YFe2D4.2 at ambient temperature and pressure is related to a distortion of the initial cubic C15 structure ofYFe2 by the ordering of inserted D atoms. A structural transition from monoclinic to cubic structure is observed at 4 GPa. The high pressure cubic YFe2D4.2 has a 19% higher cell volume than that of YFe2. The application of an external pressure leads to the progressive decrease of the transition temperature TM0 from ferro to antiferromagnetic order (TM0 = 84 K at ambient pressure) and even to the suppression of the ferromagnetic ground state for pressures larger than 0.54 GPa.
