The spin excitation gap at Landau filling factor v = 1 has been determined from thermally activated transport measurements in the limit of small Landé g ‐factor. The application of hydrostatic pressure allows to probe the region −0.11 < g < 0.055. The observed 50% reduction in the spin excitation gap at g = 0 is fully consistent with the recently proposed spin texture excitations (Skyrmions).
