Magnetic and magnetoelastic properties of LiYbF4 crystal in the strong magnetic field

This work presents the results of experimental and theoretical studies of the magnetic properties of the LiYbF4 single crystal and powder samples, and magnetoelastic properties of the LiYbF4 single crystal samples, at low temperature and applied field range of 0-9 T. The magnetostriction experimental data for the single crystal of LiYbF4 is published for the first time. The magnetization and magnetostriction were calculated in the framework of the exchange-charge model taking into account dipole-dipole and electron-deformation interactions, with the calculation of the electron-deformation parameters. The theoretical analysis presents quantitative agreement in the temperature range of 2-10 K with the magnetization and magnetostriction measurements of the LiYbF4 samples.
