New experimental approaches and theoretical results concerning the search for superfluidity in three- and two-dimensional solutions of ³He in ⁴He are reviewed. Estimates for the s-wave and p-wave pairing temperatures are given for both unpolarised and polarised cases. The role of monolayers and submonolayers of ³He as an ideal-purity two-dimensional system for experimental verification of various current theories of high-temperature superconductivity is emphasised.
