In gallium-substituted iron garnets such as are used in bubble domain memories, the measured exchange constant values are lower than the normally used exchange constant values estimated from Neel molecular field theory. The measured values bring calculated wall energies into agreement with measured wall energies. From LPE liquid phase epitaxy film growth studies, the growth temperature has been found to be more influential than the growth rate on the amount of lead incorporated into a film from the flux. A new garnet material containing no magnetic rare earths has been prepared which has an appreciable uniaxial anisotropy. Author
