Harmonics Distribution of Iron Oxide Nanoparticles Solutions under Diamagnetic Background

The static and dynamic magnetizations of low concentrated multi-core iron oxide nanoparticles solutions were investigated by a specially developed high-Tc Superconducting Quantum Interference Device (SQUID) magnetometer. The size distribution of iron oxide cores was determined from static magnetizat...
