This pinning effect is the origin of magnetic hysteresis. When the size of nanoparticle increases, the core part increases and the volume rate between the shell and core region decreases, which leads to the weakness and disappearance of the pinning effect. Thus, the spin pinning effect could be adjusted by the particle size.
