X-ray-scattering study of the two magnetic correlation lengths in uranium antimonide.

Abstract

In common with some other recent critical scattering studies we have observed the presence of a second component in the critical fluctuations close to the continuous magnetic phase transition in USb. It is found that the magnetic anisotropy of this second component does not exhibit the same directional dependence as the {open_quote}{open_quote}normal{close_quote}{close_quote} critical scattering and that the critical behavior of this feature is not consistent with an Ornstein-Zernike treatment of the scaling. {copyright} {ital 1996 The American Physical Society.}
