| description |
In BiFeO3 films, it has been found that epitaxial constraint results in the destruction of a space
modulated spin structure. For (111)c films, relative to corresponding bulk crystals, it is shown (i)
that the induced magnetization is enhanced at low applied fields; (ii) that the polarization is
dramatically enhanced; whereas, (iii) the lattice structure for s111dc films and crystals is nearly
identical. Our results evidence that eptiaxial constraint induces a transition between cycloidal and
homogeneous antiferromagnetic spin states, releasing a latent antiferromagnetic component locked
within the cycloid. |
