AB  - Fe1xRhx layers are grown with varying rhodium fraction x on (001)-oriented MgO substrates bymolecular-beam epitaxy. Film structural, morphological, magnetic, and transport properties areinvestigated. At room temperature, layers are ferromagnetic (FM) for x<0.48 and antiferromagnetic(AF) for x>0.48. Separating the two magnetically ordered phases at x¼0.48 is an abruptchange in the Fe1xRhx lattice parameter of Da¼0.0028 nm (Da/a¼0.9%). For AF layers, theFM state is recovered by heating across a first-order phase transition. The transition leads to a largeresistivity modulation, Dq/q ¼80%, over a narrow temperature range, DT¼3K, in stoichiometricFe0.50Rh0.50/MgO(001). For samples with compositions deviating from x¼0.50, fluctuationsbroaden DT and defect scattering reduces Dq/q. Published by AIP Publishing.
