Resonant Bragg diffraction of soft, circularly polarized x-rays has been usedto observe directly the temperature dependence of chiral-order melting in amotif of Mn ions in terbium manganate. The underlying mechanism uses the b-axiscomponent of a cycloid, which vanishes outside the polar phase. Melting iswitnessed by the first and second harmonics of a cycloid, and we explain whythe observed temperature dependence is different in the two harmonics. Ourdirect observation of melting is supported by a solid foundation of evidence,derived from extensive studies of the azimuthal-angle dependence of intensitieswith both linear and circular polarization.
