The influence of a magnetic field on the transition is analyzed. The estimates for the critical temperature for a trapped gas of $^6$Li atoms and $^3$He--$^4$He mixtures are presented.2 pages, 1 figure, LT22 Conference paper, phbauth and elsart style files includedStatistical MechanicsSuperconductivitytext
