Signature of spin-triplet exciton condensations in LaCoO3 at ultrahigh magnetic fields up to 600 T (IMAGE)
Caption
Figure 3 Schematic of how applying an ultra-high magnetic field to a cobalt oxide induces the magnetic "super" states. LaCoO3 has a "vacuum" (low-spin) and a "magnetic exciton" (high-spin) state. Before applying a magnetic field, all cobalt ions are in the vacuum state; when a magnetic field of up to 600 Tesla is applied, a change occurs and a magnetic superfluid or magnetic supersolid state develops. Since magnetic excitons have the property of pushing the crystal lattice apart, we observed signs of these changes with this "shrinkage" measurement. Eventually, all cobalt oxides are expected to reach a fully magnetized state, but this has not been observed in this study.
