Phase diagram of superfluid $\rm^3He$ in “nematically ordered” aerogel

Results of experiments with liquid $\rm^3He$ immersed in a new type of aerogel are described. This aerogel consists of $\rm Al_2O_3\cdot H_2O$ strands which are nearly parallel to each other, so we call it as a “nematically ordered” aerogel. At all used pressures a superfluid transition was observed and a superfluid phase diagram was measured. Possible structures of the observed superfluid phases are discussed.
