Special Issue Information

Dear Colleagues,

High-pressure research has seen a great progress during the last few decades as a consequence of the combined development of various experimental techniques and computer simulations. Recently, the number of studies of crystalline materials under high pressure has growth exponentially and the pressure range covered by them has been extremely extended reaching magnitudes of the order of Terapascals. Important discoveries have been achieved thanks to high-pressure studies. These breakthroughs concerns different research fields including solid-state physics, chemistry, and materials science among others. Metallization of hydrogen is the most recent of them. The impact of pressure on chemical and physical properties and some of the contemporary discoveries are the main reasons for producing the current Special Issue.

The Special Issue on “High-Pressure Studies of Crystalline Materials” pretends to give a forum aimed at describing and discussing recent results of high-pressure studies on structural, mechanical, vibrational, and electronic properties of crystalline materials. The intention is to give special emphasis to phase transitions and their effects on different properties, but other issues are not excluded. The Special Issue is open to both experimental and theoretical contributions. Researchers working in a wide range of disciplines are welcomed to contribute to it. The topics summarized under the keywords given below are just broadly examples of the greater number of topics in mind. The volume is especially open for any innovative contributions and also for brief reviews of current hot topics.

Title: Structural phase transition and electronic structure of wolframite-type compounds under pressure
Authors: J. Ruiz-Fuertes and D. Errandonea
Affiliation: Departamento de Física Aplicada-Instituto de Ciencia de Materiales, MALTA Consolider Team, Universidad de Valencia
Abstract: Recent research of the structural behavior and electronic structure of wolframites-type crystals under pressure has resulted into a great control of the properties of this family of compounds including from scintillators to type II multiferroics. This article reviews the developments on high-pressure performed on AWO4 among other wolframite-type and pseudo-wolframite-type oxides. The compressibility and stability range of the wolframite phase of different compounds and the structural solution of different pressure-induced post-wolframite phases will be discussed and correlated to the vibrational and electronic properties. The trends and differences of behavior of different members of the wolframite family will be presented and discussed. Finally, the effect of pressure on the magnetic structure of multiferroic wolframites and pseudo-wolframites will be introduced.

Abstract: The opposing effects of high pressure (in the GPa range) and the Jahn-Teller distortion lead to many intriguing phenomena which are still not well understood. Here we report a combined experimental-theoretical study on an archetypical Jahn-Teller system, copper difluoride (CuF2). At ambient conditions this compound adopts a distorted rutile structure of P21/c symmetry. Raman scattering measurements performed up to 30 GPa indicate that CuF2 undergoes a phase transition at 9 GPa. By comparing experimental Raman frequencies with those obtained by Density Functional Theory (DFT) calculations we assign the novel high-pressure phase to a distorted fluorite structure of Pbca symmetry. Moreover we predict that the Pbca structure should transform to a non centrosymmetric Pca21 polymorph above 35 GPa, which in turn should be replaced by a cotunnite-like phase (Pnma symmetry) at 72 GPa. Interestingly we find that the 2D character found in the ambient pressure structure of CuF2 is retained in the Pbca and Pca21 high-pressure polymorphs, while the Pnma structure stable at the highest pressures is built of 1D chains. Our results, which indicate that the strong Jahn-Teller effect found for CuF2 is not suppressed even at 100 GPa, are put into the context of previous high-pressure investigations of Jahn-Teller systems, in particular bearing Cu2+ and Ag2+ cations.
