Superparamagnetic fluctuation of magnetic nanoparticles is studied. We examine the validity of the simplified approach using the difference between zero-field-cooled magnetization and field-cooled one. The results show that it is valuable for estimating the blocking temperature distribution of polydispersive particles, even in magnetic fields, if both surface effects and inter-particle interactions are negligible.
