During more than 30 years, intensive research has been devoted to organic conductors and
superconductors. The main reason for this constant interest is certainly the large number of …

Three kinds of magnetic-resonance signals were detected in crystals of the spin-gap magnet
TlCuCl 3. First, we have found antiferromagnetic resonance absorption in the field-induced …

We investigate lattice dynamics and spin-phonon coupling as well as the magnetic and
electronic properties of β-Na 0.33 V 2 O 5 using temperature-dependent Raman scattering …

Low-dimensional magnetism physics involves the search for new magnetic compounds and
improving their characteristics to meet the needs of innovative technologies. A …

Temperature dependent optical spectra are reported for β-N a 0.33 V 2 O 5. The sodium
ordering transition at TN a= 240 K and, in particular, the charge ordering transition at TMI …

Sodium vanadate nanomaterials with the shape of belts and flakes were prepared by simply
controlling the pH from the alkaline solution of V2O5. Nanostructured materials have grown …

Quasi-one-dimensional Cr-based (d 3, S= 3 2) pyroxenes (Li, Na) Cr (Si, Ge) 2 O 6 reach
long-range magnetic order at low temperatures. At substitution of small size cations Li 1+ …

Polarized Raman spectra of the calcium vanadium oxide bronze β-Ca 0.33 V 2 O 5 are
measured in the temperature range between 300 and 20 K. The charge ordering phase …

Na 23 NMR measurements have been made on a single crystal to study the charge
disproportionation accompanied by the metal-insulator transition in the quasi-one …

We present detailed electron-spin resonance investigations on single crystals of the one-
dimensional vanadium-oxide bronze β-N a 1/3 V 2 O 5. From the angular dependence of the …
