Query: Modification of the 3He Phase Diagram by Anisotropic Disorder   Motivated by the recent prediction that uniaxially compressed aerogel can
stabilize the anisotropic A phase over the isotropic B phase, we measure the
pressure dependent superfluid fraction of 3He entrained in 10% axially
compressed, 98% porous aerogel. We observe that a broad region of the
temperature-pressure phase diagram is occupied by the metastable A phase. The
reappearance of the A phase on warming from the B phase, before superfluidity
is extinguished at Tc, is in contrast to its absence in uncompressed aerogel.
The phase diagram is modified from that of pure 3He, with the disappearance of
the polycritical point (PCP) and the appearance of a region of A phase
extending below the PCP of bulk 3He, even in zero applied magnetic field. The
expected alignment of the A phase texture by compression is not observed.
