Summary

USING THE JACOBI MATRIX METHOD DEVELOPED BY PERESADA, EFFECTS OF LIGHT-MASS IMPURITIES ON THE HEAT CAPACITY OF A STRONGLY ANISOTROPIC CRYSTAL WERE CALCULATED WITHIN A MICROSCOPIC APPROACH FOR A SPECIFIC MODEL OF THE CRYSTAL LATTICE. IT IS SHOWN THAT BECAUSE OF A SHARP LOW-FREQUENCY PEAK IN THE VIBRATION DENSITY OF STATES OF THE STRONGLY ANISOTROPIC CRYSTAL, THE LIGHT-MASS IMPURITY CHANGES ESSENTIALLY ITS PHONON HEAT CAPACITY AT LOW TEMPERATURES.
