Muon spin relaxation measurements have been performed in the two dimensional spin system SrCu2(BO3)2. As the temperature decreases, the relaxation rate increases below T=10 K , and shows a saturation below T=3 K . The line shape at low temperatures i

Muon spin relaxation has been measured in Sr(Cu1-xZnx)2O3. The results for low Zn concentration x 0 occurred with increasing x around x approximately 0.8%, accompanied by a change of line shape to that expected in a concentrated magnetic environment.

Muon spin relaxation (μSR) and high-field magnetization measurements have been performed in Ba8Si46, a superconductor with T c =8 K having a silicon clathrate three-dimensional cage structure. The upper critical field H c2 =6.5 T , determined from t

We have performed ZF-μSR measurements of Sr2RuO4 and have observed a spontaneous magnetic field below Tc. This observation, combined with other symmetry considerations demonstrates that superconductivity in Sr2RuO4 is of ‘p-wave’ (odd-parity) ty

We have measured muon spin relaxation (μSR) in (Cu1−xMgx)GeO3, a spin-Peierls compound disturbed by the Mg (S=0) doping of the Cu ( S= 1 2 ) spin chain. Static magnetic order was observed in the zero-field μSR measurements below the Neel temperat
