Quantum paramagnet near spin-state transition
K. Tomiyasu, N. Ito, R. Okazaki +11
Spin-state transition, also known as spin crossover, plays a key role in diverse systems, including minerals and biological materials. In theory, the boundary range between the low…

Microscopic examinations of Co valences and spin states in electron-doped LaCoO
Keisuke Tomiyasu, Syun-Ichi Koyama, Masanori Watahiki +12
We studied the Co valences and spin states in electron-doped LaCoTeO by measuring x-ray absorption spectra and electron spin resonance. The low-temperature insula…

Spin-state responses to light impurity doping in low-spin perovskite LaCoO
Keisuke Tomiyasu, Yuuki Kubota, Saya Shimomura +3
We studied the spin-state responses to light impurity doping in low-spin perovskite LaCoO (Co^3+: d^6) through magnetization and X-ray fluorescence measurements of single-cry…
