11. The dispersion for the spin wave of spin 1/2 fermions was first studied by V.P. Silin, Zh. Éksp. Teor. Fiz. 33, 1227 (1958) [JETP 6, 945 (1958)] and later by
12. A. J. Leggett, J. Phys. C 3, 448 (1970). Our result contradicts that of Silin [his Eq. (3.12)] but agrees with that obtained from the equations derived by Leggett.
