Abstract

We introduce our μSR investigations of spin-gap systems, such as, (1) a 2-leg spin-ladder material SrCu₂O₃, (2) a Haldane material (S = 1 spin-chain) Y₂BaNiO₅, (3) a spin-Peierls material CuGeO₃, (4) a spin-chain&ladder material Sr₆Ca₈Cu₂₄O₄₁. All of these antiferromagnetic spin systems are characterized by a spin-gap between the singlet groundstate and the triplet first excited states. In the above-mentioned materials, we confirmed the absence of magnetic order down to milli-Kelvin regime, supporting the non-magnetic feature of the ground-state. If a spin-gap system is doped with charges and/or vacancies at the spin site, unpaired spins are induced out of the singlet ground-state. In some materials, doping completely destroys the singlet ground-state and induces a bulk magnetic order. We report μSR investigations of doped materials as well, which clarifies the existence/absence of a magnetic order upon doping.
