Inhomogeneous magnetic cluster states in the magnetoresistance material Lu2V2O7
Abstract
We report Raman scattering and multifrequency (54–336 GHz) electron-spin-resonance (ESR) measurements on Lu2V2O7 single crystals in the temperature range 4–300 K with the view of understanding the origin of the large magnetoresistance in this lattice. The 307 cm−1 phonon mode undergoes a hardening at temperatures below Tm=150 K. Concomitantly, the single ESR peak arising from the paramagnetic V4+ ions becomes distorted. This is ascribed to the …
