Non-monotonic field-dependence of the ZFC magnetization peak in some systems of magnetic nanoparticles

R. Sappey, E. Vincent, N. Hadacek +3

We have performed magnetic measurements on a diluted system of gamma-Fe2O3 nanoparticles (~7nm), and on a ferritin sample. In both cases, the ZFC-peak presents a non-monotonic fiel…
