Abstract

Since the discovery of superconductivity in (La1-xBax)2CuO4 by Bednorz and Müller1 in 1986, there has been an enormous interest in all aspects of this family of materials. Our measurements have used neutron scattering techniques to study the magnetic properties of these materials. The measurements were made at the Institut Laue-Langevin in Grenoble, France, and at the Risø National Laboratory at Roskilde, Denmark. A number of studies of these types of materials have previously been made at other laboratories, particularly Brookhaven National Laboratory.2 Many of our measurements have been made on a different energy scale than the earlier measurements, and different aspects of the problem have been addressed. Where the experiments have overlapped, good agreement has generally been found.
