EHPRG

Welcome to the official website of the European High Pressure Research Group (EHPRG).

EHPRG is non-profitable academic association established in 1963 which is devoted to science and technology of matter under high pressure. It organizes an annual meeting which brings together hundreds of scientists of various fields, mainly physics, chemistry, Earth and planetary sciences, bio- and food science and technology.

The reasonable size of the group, low conference fees, and a friendly relationship between the attendants have made EHPRG meetings a major event in the European high-pressure community for more than half a century.

Selection of high-pressure related titles from top scientific journals.

In this work, the high-pressure and high-temperature (HPHT) method was applied to obtain crystalline tin disulfide (${\mathrm{SnS}}_{2}$). The synthesis was performed in a sulfur-tin-carbon growth system by placing the reaction mixture of sulfur and tin in a graphite capsule. The synthesized ${\math…

Author(s): A. Tröster, C. Verdi, C. Dellago, I. Rychetsky, G. Kresse, and W. Schranz


We investigate the properties of hard antiphase boundaries in ${\mathrm{SrTiO}}_{3}$ using machine-learned force fields. In contrast to earlier findings based on standard ab initio methods, for all pressures up to $120\phantom{\rule{0.16em}{0ex}}\mathrm{kbar}$ the observed domain wall pattern mainta…

Vibrational and elastic properties of the $R{\mathrm{Fe}}_{4}{\mathrm{Sb}}_{12}$ skutterudites are investigated by, respectively, temperature $(T)$ dependent extended x-ray absorption fine structure (EXAFS) and pressure $(P)$ dependent x-ray diffraction (XRD) experiments. The Fe $K$-edge EXAFS exper…

Inverse exchange bias effects and magnetoelectric coupling of the half-doped perovskite-type chromites ${\mathrm{Gd}}_{0.5}{\mathrm{Sr}}_{0.5}{\mathrm{CrO}}_{3}$ and ${\mathrm{Gd}}_{0.5}{\mathrm{Ca}}_{0.5}{\mathrm{CrO}}_{3}$

The ${\mathrm{Cr}}^{4+}$ oxidation state with two electrons in the $\mathrm{Cr}\phantom{\rule{0.28em}{0ex}}3d$ shell is not often observed in perovskite-type oxides, as high pressures and temperatures are generally required to stabilize the octahedral coordination. Herein, we present a comparative s…
