Order parameter of A-like He-3 phase in aerogel

In the framework of a phenomenological description of superfluid He-3 in aerogel, a criterion of choosing the form of the order parameter close to the transition is obtained. Besides the BW phase, the order parameter of the axiplanar phase with specially chosen free parameters also satisfies this criterion. Such an order parameter is proposed as limiting at T --> T-c for an A-like phase observed for He-3 in aerogel. (C) 2003 MAIK Nauka/Interperiodica.
