Abstract

The question addressed in this paper is that of the influence of the density of dislocations on the spin tunneling in (formula presented) clusters. We have determined the variation in the mosaicity of fresh and thermally treated single crystals of (formula presented) by analyzing the widening of low angle x-ray diffraction peaks. It has also been well established from both isothermal magnetization and relaxation experiments that there is a broad distribution of tunneling rates which is shifted to higher rates when the density of dislocations increases. © 2002 The American Physical Society.
