Elastic study of electric quadrupolar correlation in the paramagnetic state of a frustrated quantum magnet
Y. Nii, Y. Hirokane, S. Nakamura +4
Electric quadrupolar state in a frustrated quantum magnet has been studied by means of ultrasonic and magnetostriction measurements. A single crys…
Anomalous Hall effect at the spontaneously electron-doped polar surface of PdCoO2 ultrathin films
T. Harada, K. Sugawara, K. Fujiwara +5
We revealed the electrical transport through surface ferromagnetic states of a nonmagnetic metal PdCoO2. Electronic reconstruction at the Pd-terminated surface of PdCoO2 induces St…
Emergence of spin-orbit order in the spinel CuCrO
K. Tomiyasu, S. Lee, H. Ishibashi +6
We determined the magnetic structure of CuCrO using neutron diffraction and irreducible representation analysis. The measurements identified a new phase between 155 K and 1…
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…
