Abstract

The cuprates Cu₆Ge₆O_18-xD₂O (x 0, 6) have spin-1/2 chains with first-and second-nearest-neighbor (1NN and 2NN) antiferromagnetic (AF) exchange interactions. Magnetic long-range order (LRO) appears below 74 and 39 K for x 0 and 6, respectively. We observed two magnetic Bragg peaks in each sample in neutron diffraction measurements on powder samples. These peaks indicate appearance of collinear AF LRO. We confirmed that both the 1NN interaction and nearest-neighbor interchain interaction were AF.
