The dynamics of many discontinuous phase transitions is determined by the nucleation and growth of regions of the new phase. Katsufuji et al. demonstrate that the orbital ordering transition of doped BaV10O15 presents an electronic example of nucleat

We review recent advances in strongly correlated oxides as thermoelectric materials in pursuit of energy harvesting. We discuss two topics: one is the enhancement of the ordinary thermoelectric properties by controlling orbital degrees of freedom and

In BaV_{10}O_{15} with quasitriangular V lattices, we found unique superstructures characterized by (qq0)-type peaks in the momentum space, where q varies continuously with temperature between q=0 and 1/3 and locks at 1/3. Such a threefold superstruc

Abstract The simultaneous occurrence of the structural and magnetic phase transitions observed in MnV2O4 is one clear example of strong interplay among the spin, orbital and lattice degrees of freedom. The structure of MnV2O4 is switched by the magne

We studied the ferrimagnet La_{5}Mo_{4}O_{16} with Mo ions on quasisquare lattices both experimentally and theoretically. We found that in addition to the antiferromagnetic ordering at T_{N}=200 K, a magnetic phase transition into a ferrimagnetic pha

The chiral crystal of enantiomeric (S)-N-3,5-di-tert-butylsalicylidene-1-phenylethylamine in the enol form [enol-(S)-1] undergoes a reversible single-crystal-to-single-crystal (SCSC) phase transition at Tc ≈ 3 °C from the room temperature α-form
