%X We investigate the spin rotational structure of magnetic skyrmions in a tetragonal polar magnet VOSe2O5 viapolarized small-angle neutron scattering (SANS). Spin polarization analysis of the scattered neutrons provides consistentevidence for the cycloidal spin modulation in all the incommensurate phases at zero and non-zero magnetic field alongthe c axis, including the triangular skyrmion-lattice phase. In the vicinity of the skyrmion phase, we performed extensiveSANS measurements to unravel a field-induced incommensurate phase (IC-2 state). We discuss the possibility ofanisotropic double-q state as an alternative spin structure to provisional square skyrmion-lattice state.
