Pressure effect on the ground state of Gd 3+ ions in the low symmetry crystal KY(WO 4 ) 2 + 0.5% Gd has been studied by means of EPR method. The parameters of the spin‐Hamiltonian of monoclinic symmetry describing the EPR spectrum and their changes under pressure were determined. All four structural positions of the Gd 3+ ion are magnetically equivalent. The direction of maximum splitting of the EPR spectrum has a deviation of about 20° from the c ‐axis. The initial splitting of Gd 3+ ion ground state is established to increase under pressure.
