Pressure-Induced Electronic Transition in CeAl2sly reported for the temperature-dependence of the resistivity under pressure up to 15 kBar by Nicolas-Francillon et al. It has been found that these anomalies gradually disappear with even higher pressures. They are entirely suppressed at pressures exceeding ?120 kBar resulting in a R-T characteris

Theoretical Approach to the Configuration Fluctuation in Sm-Chalcogenidesn terms of an essentially localized or excitonic picture of most of the Sm 5d-electrons, with a small number (?.1 electrons per Sm) occupying the free-electron-like states at the bottom of a broad 5d-band. We review how such an essentially localized model for the 5d-electrons can lead to the observe

The α-γ Phase Transitions in Ce-Th Alloys under High Pressure earth ion in these materials undergoes a change of valence in response to a temperature, pressure, or alloying variation. In the Sm mixed valence systems the atomic-like 4. state is usually situated energetically below the 5.-6. conduction band. As the temperature, pressure, or composition is varie

Pressure Dependence of Crystal Field Parameters in Rare Earth Intermetallic Compoundspansion of compounds exhibiting CEF-effects in their thermal properties. We demonstrate this for the singlet ground state systems PrSb and TmSb and for the two-level systems SmSb and CeTe. The results are in disagreement with expectations from a simple effective point charge model. They demonstrate

Pressure Dependence of Raman Scattering in Ferroelectrics and Ferroelasticsthe pressure dependence of Raman and Brillouin scattering have been investigated are summarized. Special emphasis is given to three important systems: the coupled-proton-optic mode in hydrogen bonded ferroelectrics of the KDP class, the tricritical behavior in the ferroelectric SbSI, and optic-acous
