1. Charge ordering and dimerization of magnetic spins in spinel: investigation of crystal lattice dynamics and detection of octameric correlations.
Dr. Volodymyr P. Gnezdilov et al. (Phys. Rev. Materials, V. 8, P. 095002, (2024))
New fundamental properties of extraordinary ordering in the spinel CuIr2S4, which has no precedent in three-dimensional compounds,
have been discovered. The phenomenon occurs in the low-temperature crystal lattice of three-line symmetry
CuIr2S4, which is crucial for octamer formation and orbitally controlled Peierls distortions. The defects and
impurities influence to the formation of the octameric superstructure has also been clarified. The effects,
what indicate the gradual evolution of the ideal octameric superstructure during cooling, have been observed.
2. Magnetic properties of paramagnetic magnetoelastic KEr(MoO4)2 in a strong magnetic field.
K. Kutko, V. Khrustalyov et al. (Phys. Rev. B 109, 024438 (6pp), (2024))
New fundamental data of the magnetic field influence on the crystal lattice deformation of the magnetoelastic
KEr(MoO4)2 due to changes in electron wave functions and magnetic anisotropy of the crystal have been obtained.
These information is important for uncovering of the giant magnetostriction occurrence mechanisms. It can be useful
for the creation of the latest multifunctional materials based on this compound.
