Magnetic order and muon motion in VO2

We report the first transverse, longitudinal and zero field measurements performed on Vanadium Dioxide (VO2) where we find a significant local magnetic field below T 34.7 ± 0.16 K at the muon site and Mud motion above 340 K. Distinct shifts in the muon relaxation rates and Kubo-Toyabe delta paramete...

Description
Summary:We report the first transverse, longitudinal and zero field measurements performed on Vanadium Dioxide (VO2) where we find a significant local magnetic field below T 34.7 ± 0.16 K at the muon site and Mud motion above 340 K. Distinct shifts in the muon relaxation rates and Kubo-Toyabe delta parameters, near the metal to semiconductor and structural transition (TMST ≈ 340 K), show that μ+SR measurements may provide additional means to further characterize the mechanisms contributing to these transitions that are yet to be understood.
