Structural, Magnetic and Vibrational Properties of Van Der Waals Ferromagnet CrBr3 at High Pressure

Olga Lis et al.

Summary: The crystal and magnetic structures of CrBr3 were studied at high pressures using X-ray and neutron diffraction techniques, and the vibration spectra were studied using Raman spectroscopy. An anomalous pressure behavior of structural parameters and vibrational modes was observed, indicating a gradual isostructural phase transition. The Curie temperature decreased rapidly with increasing pressure, and a complete suppression of the ferromagnetic state was expected at a critical pressure. Anomalies in Raman spectra at a certain pressure point to another possible phase transformation in CrBr3, which may be related to the proximity of metallization.

Pressure-induced coupled structural-electronic transition in SnS2 under different hydrostatic environments up to 39.7 GPa

Xinyu Zhang et al.

Summary: In this study, the vibrational and electrical transport properties of SnS2 were investigated under different conditions. The results showed that the coupled structural-electronic transition in SnS2 occurred at different pressures depending on the environment. Additionally, the theoretical calculations agreed well with the experimental results, indicating a decrease in the bandgap energy of SnS2 with increasing pressure.

Meiling Hong et al.

Summary: This study investigated the high-pressure behavior of CrCl3 under different hydrostatic conditions using various experimental techniques and theoretical calculations. The results revealed an isostructural phase transition at 9.9 GPa under nonhydrostatic conditions and a pressure delay effect under hydrostatic conditions. The phase transformation from metal to semiconductor in CrCl3 was found to be reversible, and a pressure hysteresis effect was observed under different hydrostatic environments.

Stress-induced high-Tc superconductivity in solid molecular hydrogen

Xianqi Song et al.

Summary: By first-principles calculations, this study reveals that solid molecular hydrogen compressed to ultrahigh pressures can sustain large anisotropic compressive or shear stresses, causing major crystal symmetry reduction and charge redistribution, and ultimately promoting superconductivity. This finding has important implications for exploring similar phenomena in hydrogen-rich compounds and other molecular crystals.

Pressure-induced metallization in the absence of a structural transition in the layered ferromagnetic insulator Cr2Ge2Te6

Weizhao Cai et al.

Summary: This study reports the crystallographic and electrical transport properties of single crystals of the ferromagnetic 2D material Cr2Ge2Te6 under high pressure. The results show a distinct and irreversible crystalline-amorphous transformation in Cr2Ge2Te6, with the crystalline phase and amorphous state coexisting even at the maximum pressure of 31.2 GPa. An insulator-to-metal transition is observed at -3.9 GPa, significantly lower than previously reported pressures. This study provides insights into the phase stability and metallization pressure of Cr2Ge2Te6, and demonstrates the use of pressure to tune the physical properties of 2D ferromagnetic compounds.

Summary: Using high-pressure techniques, a two-dimensional semiconductor has been transformed into a three-dimensional superconductor with excellent performance. The enhancement of interlayer coupling and bonding between interlayer atoms contributes to the emergence of nonlayered structures. This study is significant for understanding the relationship between dimensionality, structure, and superconductivity in TMDs.

Exotic magnetic and electronic properties of layered CrI3 single crystals under high pressure

Anirudha Ghosh et al.

Summary: By advanced experimental techniques and theoretical calculations, we have investigated the pressure-temperature phase diagram of CrI3 single crystals and found that pressure can effectively control the magnetic and electrical properties of this material. Pressure reduces the ordering temperature of CrI3 and induces a transition from ferromagnetism to antiferromagnetism, as well as a phase transition from semiconductor to metal.

Summary: The study presents experimental evidence of negative thermal expansion and strong spin-phonon coupling effects in the two-dimensional van der Waals material CrBr3, caused by the long-range ferromagnetic order. Anomalous temperature variation of lattice parameters and vibrational modes as well as unusual broadening of the modes below the Curie temperature (TC) were observed through neutron, X-ray diffraction and Raman spectroscopy measurements.

Pressure-induced 1T to 3R structural phase transition in metallic VSe2: X-ray diffraction and first-principles theory

Srishti Pal et al.

Summary: The study investigates the pressure-induced structural evolution of vanadium diselenide using synchrotron-based powder x-ray diffraction and first-principles density functional theory. Anomalies in the c/a ratio, V-Se bond length, and Se-V-Se bond angle were observed at around 4 GPa, indicating an isostructural transition, followed by a first-order structural transition at around 11 GPa. Changes in the Debye-Waller factors were associated with these transitions, and spin-polarized calculations with Hubbard correction were able to capture the 1T to 3R transition with a transition pressure close to the experimental value.
