Incommensurate magnetic order in Ag$_{2}$NiO$_{2}$ (2006)
Sugiyama, J., Ikedo, Y., Mukai, K., Brewer, J. H., Ansaldo, E. J., Morris, G. D., ...
The nature of the magnetic transition of the half-filled triangular antiferromagnet Ag$_{2}$NiO$_2$ with $T_{\rm N}$=56K was studied with positive muon-spin-rotation and relaxation ($\mu^+$SR)...
Evidence of Two Dimensionality in Quasi-One-Dimensional Cobalt Oxides (2006)
Sugiyama, J., Nozaki, H., Ikedo, Y., Mukai, K., Andreica, D., Amato, A., ...
The quasi-one-dimensional (Q1D) cobalt oxides A_{n+2}Co_{n+1}O{3n+3} (A = Ca, Sr, and Ba, n = 1-∞) were investigated by muon-spin spectroscopy under applied pressures of up to 1.1 GPa. The...
Generation of low-energy muons with laser resonant ionization (2006)
Matsuda, Y, Bakule, P, Iwaskaki, M, Myake, Y, Ikedo, Y, Strasser, P, ...
We have constructed a low-energy muSR spectrometer at RIKEN-RAL muon facility in ISIS, the UK. With low-background of pulsed muon beam, and short pulse width from laser resonant ionization method, it...
Isolated hydrogen center in wide gap semiconductors studied by muSR (2006)
Shimomura, K, Kadono, R, Nishiyama, K, Watanabe, I, Suzuki, T, Pratt, FL, ...
Static magnetic order in metallic K$_{0.49}$CoO$_{2}$ (2005)
Sugiyama, J., Nozaki, H., Ikedo, Y., Mukai, K., Brewer, J. H., Ansaldo, E. J., ...
By means of muon spin spectroscopy, we have found that K$_{0.49}$CoO$_2$ crystals undergo successive magnetic transitions from a high-T paramagnetic state to a magnetic ordered state below 60 K and...
