The phase separation effects in a pseudospin-electron model
The two-sublattice pseudospin-electron model of high temperature superconductors is studied with respect to phase separations. Such a model can be used for the description of dielectric properties of YBaCuO-type crystals along c -axis (the pseudospins represent an anharmonic motions of apical ox...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The two-sublattice pseudospin-electron model of high temperature superconductors
is studied with respect to phase separations. Such a model can
be used for the description of dielectric properties of YBaCuO-type crystals
along c -axis (the pseudospins represent an anharmonic motions of
apical oxygen O4). The model is treated within different approximations. It
is shown that the model has got phase transitions to the phase with pseudospin
ordering as well as phase separation. The effect of separation on
the appearance of the ordered state is discussed. |
