– Zero-field Fe NMR spectrum has been observed in the Fe-enriched ceramics of BiFeO3. The analysis of NMR lineshape confirms the existence in this ferroelectricantiferromagnetic 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. BiFeO3 has been known since the 1960s as a ferroelectric-antiferromagnet exhibiting both long-range magnetic and electric… CONTINUE READING
