Abstract
A typical Ising spin-glass Fe0.5Mn0.5TiO3 has been investigated by μ+ spin relaxation measurements. It is found that the local magnetic fields at the μ+ stopping sites appear at a temperature twice as high asT SG. The directional distribution of the local magnetic fields is nearly isotropic, indicating the existence of the transverse spin components. It is clearly demonstrated that the spins fluctuate belowT SG and even at ∼4 K. Taking into account the results obtained by other methods, the main part of the fluctuations is inferred to be due to the transverse spin components and the fluctuation limes at ∼4 K are driven into a range between ∼10−5 and ∼10−7 s.
