摘要: In this paper, we compared the results of a heat capacity study an erbium-doped gallium gadolinium garnet crystal with data for undoped garnet. The measurements were carried out in temperature range from 1.9 to 220 K and magnetic fields 0 9 T. dependences specific interpreted allowance Schottky contributions due Gd3+ Er3+ ions thermal vibrations lattice. values entropy are calculated.
