Ferromagnetic excess moments and apparent exchange bias in FeF(2) single crystals

The anisotropic antiferromagnet FeF(2) has been extensively used as an antiferromagnetic layer to induce exchange bias effects in ferromagnetic/antiferromagnetic bilayers and heterostructures. In this work, an apparent exchange bias occurring in the low temperature hysteresis loops of FeF(2) single...

description The anisotropic antiferromagnet FeF(2) has been extensively used as an antiferromagnetic layer to induce exchange bias effects in ferromagnetic/antiferromagnetic bilayers and heterostructures. In this work, an apparent exchange bias occurring in the low temperature hysteresis loops of FeF(2) single crystals is investigated. A detailed investigation of the hysteresis and remnant magnetization indicates that the observation of an apparent exchange bias in FeF(2) stems from an intrinsic excess moment associated with a distortion of the antiferromagnetic structure of piezomagnetic origin.
