B-phase in a strong magnetic field (B$_2$-phase)

Data for the A-B transition in a magnetic field came from Inseob Hahn PhD thesis (see also He3-calculator http://spindry.phys.northwestern.edu/he3.htm). An approximation problem have been fixed near $P=21.2$ bar.

Gap distortion and spin polarization is calculated according with Ashida and Nagai paper (Progr.Theor.Phys. 74 949 (1985)).
