Abstract

Neutron scattering measurements for YBa₂Cu₃O_6.6 have identified small magnetic moments that increase in strength as the temperature is reduced below T^* and further increase below T_c. An analysis of the data shows the moments are antiferromagnetic between the Cu-O planes with a correlation length of longer than 195 \AA in the a-b plane and about 35 \AA along the c axis. The origin of the moments is unknown, and their properties are discusssed both in terms of Cu spin magnetism and orbital bond currents.
