【 摘 要 】

Temperature and magnetic field dependences of the magnetization of LiDyF4single crystal were measured with a dc-SQUID magnetometer. The longitudinal magnetostriction was measured by the capacitance-bridge method. A giant compression of the crystal lattice up to 0.1% was observed in the magnetic field of 1 T along the [110] direction at 4.2 K. Experimental data are well reproduced by simulations based on the microscopic models of the single-ion magnetoelastic and inter-ion multipole interactions.
