In fact, the samples with the smallest particles (Mn 0.17 -20 and Co 0.07 Zn 0.04 -18) become virtually unhysteretic and therefore very close to the superparamagnetic state at room temperature. Only the sample Co 0.09 -23 keeps a quite significant hysteresis at RT corresponding to larger values of the remanent magnetization (0.39) and coercive field (13.6 mT).
