Anisotropic aerogel possesses structure which exhibits a strong influence over the composition and orientation of the order parameter of imbibed superfluidHe. Computational studies have identified stretched aerogel with plane-like structures and compressed aerogel with nematic-like structures. Studies of theBphase of superfluidHe in stretched aerogel display an enhanced nuclear magnetic susceptibility likely caused by Andreev bound states near plane-like impurity sites. We report further details on the influence of these planar structures on both magnetic and orbital orientation transitions. The orbital orientation transitions appear in both theBandAphases of stretched and compressed aerogels. These transitions result from a crossover of the superfluid coherence length with long and short length scale structure with the coherence length and are consequently magnetic field independent. Additionally, the apparent temperature-independence of the susceptibility of theBphase, equal to that of theAphase in stretched aerogel and indicative of a near-isentropic transition, is in marked contrast with the field dependence of the superfluidAtoBphase transition.
