title: Strain and Magnetic Field Induced Spin-Structure Transitions in Multiferroic BiFeO3.
abstract: The magnetic-field-dependent spin ordering of strained BiFeO3films is determined using nuclear resonant scattering and Raman spectroscopy. The critical field required to destroy the cycloidal modulation of the Fe spins is found to be significantly lower than in the bulk, with appealing implications for field-controlled spintronic and magnonic devices.
