Abstract

Neutron-diffraction and small-angle scattering techniques have been used to study the magnetic properties of ErBa2Cu3O7. Below the superconducting transition of 95 K there is a decrease in the small-angle scattering, which has the correct amplitude, temperature dependence, and q dependence to be interpreted as the screening of the paramagnetic fluctuations by the superconducting electrons. At low temperatures (K) the Er moments become ordered two dimensionally, with chains of spins coupled ferromagnetically, while adjacent chains align antiparallel.
