Magnetoelastic Effects and Magnetization in LiDyF4 and LiHoF4 Single Crystals

摘要

Temperature and magnetic field dependences of the magnetization of LiHoF4 and LiDyF4 single crystals were measured with a dc-SQUID magnetometer MPSM-2 (Quantum Design) with the magnetic field applied along and perpendicular to the c axis. Experimental data are well reproduced by simulations based on the microscopic model of the crystal field and magnetoelastic interactions.
