We measured cw-NMR of superfluid He-3-A in cylindrical cells with diameters
of 0.1 and 0.2 mm under rotation. A new satellite signal was observed only
in the 0.2 mm cell when the liquid was cooled through T-c under rotation b
ut was not observed when it was cooled without rotation. The angular veloci
ty of rotation is too low to create one vortex line in the cylinder and thu
s the satellite signal may be due to the spin wave of the Mermin-Ho texture
