Zigzag chain order of LiVSe developing away from the vanadium trimer phase transition boundary
K. Kojima, N. Katayama, K. Sugimoto +3
The phenomenon of self-assembly of constituent elements to form molecules at low temperatures appears ubiquitously in transition metal compounds with orbital degrees of freedom. Re…
Observation of local atomic displacements intrinsic to the double zigzag chain structure of 1T-MTe2 (M = V, Nb, Ta)
N. Katayama, Y. Matsuda, K. Kojima +7
We describe the existence of local distortion discovered in the synchrotron x-ray single-crystal structure analysis of layered ditelluride 1T-MTe2 (M = V, Nb, Ta). In 1T-TaTe2, the…
Short-range order and increased transition temperature in LiVO2 with weakened trimer frustration
K. Kojima, N. Katayama, Y. Matsuda +3
Vanadium atoms in layered LiVO2 form in-plane periodic vanadium trimers at low temperatures, but the trimers appear randomly in the stacking direction because there are many trimer…
Charge-ordered state satisfying the Anderson condition in LiRh2O4 arising from local dimer order
Manabu Shiomi, Keita Kojima, Naoyuki Katayama +8
We report on the charge-ordered structure of LiRh2O4 arising below the metal-insulator transition at 170 K. Structural studies using synchrotron X-rays have revealed that the charg…
