Homogeneous spin precession in superfluid He-3 confined to aerogel

摘要

We report on systematic studies of creation and relaxation of a macroscopic region of homogeneous spin precession (homogeneously precessing domain-HPD) in B-like phase of He-3 in aerogel. Long lived free induction decay signal has been observed after filling up the whole cell with the HPD and switching off the CW radiofrequency field. Characteristics of CW NMR and free induction decay signal were found to be similar to those known for bulk He-3-B. (C) 2003 Elsevier Science B.V. All rights reserved. [References: 8]
