Mesoscopic orbital paramagnetism: The role of zero-point energy

Observation of Room-Temperature Ferromagnetism Induced by High-Pressure Hydrogenation of Anatase TiO2

“…where x = Cμ 0 H, and C is the initial slope of the reduced magnetization curve. 51 Fits of eq 3 to the VSM RTmagnetization curve corresponding to the TiO 2 -H2-P40 sample (Figure 5b) give fit parameters C = 4.22 ± 0.06 T −1 and M S = 9.54 ± 0.04 A/m, which are very similar to those reported for pure CeO 2 nanoparticles by Coey et al 6 Raman Spectroscopy. To detect the structural modifications introduced by thermal treatments, we performed Raman scattering measurements (see spectra in Figure 6a).…”

“…This frame has previously been used in the context of Au thin films and nanoparticles , and ZnO and CeO 2 nanoparticles . Based on the GOP model, the magnetization curve can be adjusted to the expression where x = C μ 0 H , and C is the initial slope of the reduced magnetization curve . Fits of eq to the VSM RT-magnetization curve corresponding to the TiO 2 -H2-P40 sample (Figure b) give fit parameters C = 4.22 ± 0.06 T –1 and M S = 9.54 ± 0.04 A/m, which are very similar to those reported for pure CeO 2 nanoparticles by Coey et al…”
