Tuning the core−shell morphology of bimagnetic nanoparticles and its associated exchange bias behavior is a promising way to overcome the superparamagnetic limit and stabilize the particle moment in extended time and temperature ranges. We report a significant nonzero magnetization in the CoxFe(1−x)O core of native core−shell bimagnetic nanoparticles that is typically considered antiferro- or paramagnetic.
