“…The calculations with the CF parameters for YAl 3 (BO 3 ) 4 :Tm 3+ from [23] and their comparison with the magnetic characteristics measured in our experi ments show a substantial difference between the resultant anisotropy of magnetization and the experi mental value. The magnetization curve M c (B) calcu lated for the field direction B || c and temperature dependences M c (T) for B = 0.1-9.0 T are found to be much lower than the experimental curves.…”

“…Although alumoborate YAl 3 (BO 3 ) 4 :Tm 3+ and not TmAl 3 (BO 3 ) 4 was studied in [23], the energy level diagrams (order of doublets and singlets as well as their numbers) should not differ sig nificantly for these two compounds; the values of spe cific splitting between the levels can be different.

The thermodynamic properties of alumoborate TmAl 3 (BO 3 ) 4 single crystal are studied experi mentally and theoretically. A theoretical analysis based on the crystal field model makes it possible to interpret all measured parameters. The crystal field parameters are determined. The temperature (3-300 K) and field (up to 9 T) dependences of magnetization are described. The field and temperature dependences of multipole moments of the Tm 3+ ion in TmAl 3 (BO 3 ) 4 make it possible to describe magnetostriction and low temperature anomalies in thermal expansion.

Terahertz spectroscopy of crystal-field transitions in magnetoelectric TmAl3(BO3)4

et al. 2016

Dynamic magnetic properties of magnetoelectric TmAl 3 (BO 3 ) 4 borate have been investigated by terahertz spectroscopy. Crystal field (CF) transitions within the ground multiplet 3 H 6 of Tm 3+ ions are observed and they are identified as magnetic-dipole transitions from the ground singlet A 1 to the next excited doublet E of Tm 3+ ions. Unexpected fine structure of the transitions is detected at low temperatures. The new modes are assigned to local distortions of the sites with D 3 symmetry by Bi 3+ impurities, which resulted in the splitting of A 1 →E transi on. Two types of locally distorted sites are identified and investigated. The main contribution to the static magnetic susceptibility is shown to be determined by the matrix elements of the observed magnetic transitions. We demonstrate that even in case of local distortions the symmetry of the undistorted crystal is recovered for magnetic and for quadratic magnetoelectric susceptibilities.
