Abstract The two-dimensional van der Waals (vdW) magnets retaining magnetic order in atomically thin limit demonstrate challenging physical phenomena and they are considered as prospective building blocks for construction of advanced spintronics nanoelectronics devices. Here, we present experimental evidence negative thermal expansion lattice volume vdW layers strong spin–phonon coupling effects, caused by formation the long-range ferromagnetic material CrBr 3 . neutron X-ray diffraction...
Among the recently discovered 2D intrinsic van der Waals (vdW) magnets, Fe3 GeTe2 (FGT) has emerged as a strong candidate for spintronics applications, due to its high Curie temperature (130 - 220 K) and magnetic tunability in response external stimuli (electrical field, light, strain). Theory predicts that magnetism of FGT can be significantly modulated by an strain. However, experimental evidence is needed validate this prediction understand underlying mechanism strain-mediated vdW system....
The crystal and magnetic structures of van der Waals layered ferromagnet CrBr3 were studied using X-ray powder diffraction neutron at pressures up to 23 GPa ambient temperature 2.8 in the range 6–300 K, respectively. vibration spectra Raman spectroscopy temperature. anomalous pressure behavior structural parameters vibrational modes was observed, associated with a gradual isostructural phase transition 2.5–7 GPa.

The crystal structure and vibrational spectra of CoFe 2 O 4 ferrite were studied using X-ray diffraction Raman spectroscopy over a pressure range 0–35[Formula: see text]GPa. A structural phase transition from the cubic [Formula: text] to post-spinel orthorhombic Bbmm occurs at approximately 23[Formula: text]GPa through two-phase region. Pressure-induced changes in parameters, lattice distortion, modes investigated detail. Lattice bond lengths, compressibility, bulk modulus for both phases determined.
The laser oscillation of tetravalent chromium and scandium codoped forsterite Cr4+,Sc:Mg2SiO4 single crystal has been demonstrated for the first time continuous wave, tunable mode-locked regimes. For comparison, experiments have also performed in same configuration with reference solely doped by chromium. aim codoping is to inhibit formation parasitic trivalent crystal. demonstrates a wider tuning range, lower lasing threshold spectrum than those crystal, although total efficiency achieved...
