Abstract
We report zero-field (ZF) mu SR on a series of antiferromagnetic (AFM) samp les of YBa2Cu3O6.4 reacted with water. We find several oscillating signals whose amplitudes vary with water content and temperature, and for high wate r contents, a non-oscillating component. The Neel transition is 395(5) K, c haracteristic of the undoped CnO(2) bilayer. Initial comparison with ZF mu SR and ZFNMR measurements in related AFMs (PrBa2Cu3O7 and H doped YBa2Cu3O7 ) suggests a similar muon site and an AF structure which is similar, but di stinct from YBa2Cu3O6.
