Anomalous phase of MnP at very low field (2009)
Yamazaki, T, Tabata, Y, Waki, T, Nakamura, H, Matsuura, M, Aso, N
Manganese phosphide MnP has been investigated for decades because of its rich magnetic phase diagram. It is well known that the MnP exhibits the ferromagnetic phase transition at $\Tc=292$ K and the...
Mean-field type Ising spin glass in a diluted rare-earth intermetallic compound (2009)
Tabata, Y, Matsuda, K, Kanada, S, Waki, T, Nakamura, H, Sato, K, ...
We have investigated a phase transition of a long-range RKKY Ising spin glass \dyyrusi by means of the dc and the ac magnetization measurements. The static nonlinear susceptibility $\chi_{2}$...
Spin Singlet Formation from S = 1/2 Tetrahedral Clusters (2009)
Waki, T., Kajinami, Y., Tabata, Y., Yoshida, M., Takigawa, M., Watanabe, I., ...
Muon spin relaxation ($\mu$SR) and nuclear magnetic resonance (NMR) experiments revealed that the spin singlet state with an excitation gap of $\sim$200 K is realized from $S = 1/2$ Nb$_4$...

Site-Selective NMR in the Quasi-1D Conductor beta-Sr0.33V2O5 (2006)
Waki, T., Takigawa, M., Yamauchi, T., Yamaura, J., Ueda, H., Ueda, Y.
We report 51V NMR experiments in the metallic phase of the quasi-one-dimensional (1D) conductor beta-Sr0.33V2O5. The Knight shift and the quadrupole splitting of all six vanadium sites were...
Possible Spin-triplet Superconductivity in NaxCoO2yH2O - 59Co NMR Study (2003)
Kato, M., Michioka, C., Waki, T., Itoh, Y., Yoshimura, K., Ishida, K., ...
We report 59Co NMR studies on the magnetically oriented powder samples of Co-oxide superconductors NaxCoO2yH2O with Tc ~ 4.7 K. From two-dimensional powder pattern in the NMR spectrum, the ab-plane...
