Zero-field NMR spectrum has been observed in the -enriched ceramics of . The analysis of NMR lineshape confirms the existence in this ferroelectric-antiferromagnetic compound of a long-period cycloidal magnetic structure and enables the first reconstruction of the actual spatial spin distribution along the cycloid which is found to be essentially anharmonic.
