Antiferromagnetic nuclear resonance and nuclear quadrupole resonance of Cu in Pb2Sr2RECu3O8+δ (RE=Y, Eu and Gd)

Description
Nuclear magnetic resonance of 63/65Cu in the antiferromagnetic Pb2Sr2RECu3O8+δ (RE=Y, Eu and Gd) was observed in zero external field. In the insulating state with antiferromagnetically ordered Cu moments, the other set of NQR signals was observed around 30 MHz, indicating that the transferred hyperfine field from Cu moments in the Cu-O pyramids is canceled out at the Cu nuclei in the oxygen-free Cu plane site. The results show that the magnetic Cu moments exist only at the Cu-O pyramidal site with the 3d9 state and that the Cu ion at the oxygen-free plane site is nonmagnetic (d10) in the insulating Pb2Sr2RECu3O8+δ.
