Abstract

Muon spin relaxation (μSR) measurements were carried out on La₂Cu₂O₅, which is a candidate for the spin 1/2 4-leg Heisenberg antiferromagnetic ladder system. At room temperature, the μSR spectrum can be fitted with the static Gaussian Kubo-Toyabe function. This spectrum originates from static nuclear dipole fields of copper. At approximately 140 K, a sudden decrease of the initial asymmetry was observed. This suggests that a long-range magnetic ordering of the Cu²⁺ spins occurs due to nonnegligible interladder interactions.
