Temperature-dependent magnetic measurements are reported for 4.34 nm antiferromagnetic nanoparticles mineralized in the Listeria innocua Dps protein cage. ac measurements show a superparamagnetic blocking temperature of roughly 5.4 K and give an extracted anisotropy energy density of . The Néel temperature for the nanoparticles, determined with dc magnetometry, was determined to be roughly .
