【 摘 要 】

Muon spin rotation measurements have been carried out in a stoichiometric spin ladder compound NaV2O5 in the temperature range from 2 to 300 K, through the spin-gap transition at T-c = 35 K, in transverse magnetic fields from 0.3 to 7 T. Antiferromagnetic order with a local magnetic field at a muon site of about 0.17 T is detected coexisting with the spin-gap state below 15 K. Above 20 K, the signature of a spin-polaron state is observed, which persists to about 100 K.
