Abstract
Nuclear quadrupole resonance (NQR) experiments on tetragonal YBa2Cu3Ox with x = 6.3 and 6.4 reveal a successive magnetic transition associated with the chain site at 20 K well below TN ˜ 400 K, while such transition has not been observed down to 1.3 K for x = 6.1. The second transition appears in the vicinity of the superconductivity.
