Abstract:
Single crystals of trigonal neodymium scandoborate NdSc$_3$(BO$_3$)$_4$ were grown by the group method from a solution-melt based on bismuth trimolybdate. The molar heat capacity $C(T)$ was studied in the temperature range 2–300 K and magnetic fields up to 9T. The experimental curve was approximated by the combined Debye–Einstein model. The lattice contribution was determined from ab-initio calculations. Schottky anomaly was observed in the low-temperature region $C(T)$ with the applied magnetic field.
