Description:

(abstract)

Local magnetic field studies of vanadium dioxide (VO2), which has a spin-singlet phase under the metal-insulator transition at 340 K, were performed using uSR method. By comparing the results of two samples with different qualities, it was discovered that a nonmagnetic state and microscopic magnetic ordered states coexist in the spin-singlet phase. This may be attributed to crystal lattice
imperfections inherent in VO2.
