Kinetic Characteristics of Phonons and the Structural Heterogeneities of the Monoaluminate Y1 –xErxAlO3 Solid Solutions

The low-temperature specific heat, the transport characteristics of phonons at the helium temperatures, and the nanostructural heterogeneities in the erbium monoaluminate YAlO3:Er solid solution single crystals synthesized by directional solidification are studied.
