ABSTRACT:
Using a microscopic model and the
replica method as well as the Green’s function theory, we have investigated the relaxor and multiferroic behavior of CdCr2S4.
The magnetization, the remanent polarization Pr and the real part of the dielectric function are studied
theoretically as a function of temperature, with and without a magnetic field,
respectively. The magnetization and the polarization exist together below the
magnetic phase transition temperature. Pr decreases whereas increases and the peak
shifts to smaller temperature values with increasing magnetic field h. Moreover, the temperature and
electric field E dependence of the
magnetization M is also discussed. A
kink is observed around the ferroelectric transition temperature. The kink is
deeper for stronger electric fields and anharmonic spin-phonon interactions.
