“…Such features include the cycloid anharmonicity, [ 96 ] calculating phase diagrams, [ 96,97 ] and predicting novel propagation vectors. [ 79,91,113 ] Moreover, the Landau formulation can be used to determine the equations of motion and thus calculate the spin wave excitations (further discussed in Section 4.3). [ 114,115 ]…”

Bismuth ferrite (BiFeO3) is one of the most widely studied multiferroics. The coexistence of ferroelectricity and antiferromagnetism in this compound has driven an intense search for electric‐field control of the magnetic order. Such efforts require a complete understanding of the various exchange interactions that underpin the magnetic behavior. An important characteristic of BiFeO3 is its noncollinear magnetic order; namely, a long‐period incommensurate spin cycloid. Here, the progress in understanding this fascinating aspect of BiFeO3 is reviewed, with a focus on epitaxial films. The advances made in developing the theory used to capture the complexities of the cycloid are first chronicled, followed by a description of the various experimental techniques employed to probe the magnetic order. To help the reader fully grasp the nuances associated with thin films, a detailed description of the spin cycloid in the bulk is provided. The effects of various perturbations on the cycloid are then described: magnetic and electric fields, doping, epitaxial strain, finite size effects, and temperature. To conclude, an outlook on possible device applications exploiting noncollinear magnetism in BiFeO3 films is presented. It is hoped that this work will act as a comprehensive experimentalist's guide to the spin cycloid in BiFeO3 thin films.

“…Anharmonicity in the cycloid seems to precede homogeneous order at the critical field. [ 113 ] The cycloid anharmonicity also shows a dependence on applied magnetic field, temperature (as discussed below), epitaxial strain, and domain structure. For instance, Palewicz et al.…”
