Description

Magnetic characteristics of both interacting and noninteracting Fe nanoparticle systems synthesized inside LaAlO3 matrices were investigated, utilizing SQUID magnetometry. The origin of the magnetic memory effect was explored. We found that not the interaction between magnetic nanoparticles but the size distribution is mainly responsible for that effect. Transmission electron micrographs support the finding by recording the FC/ZFC magnetization to evidence our illumination.
