AB  - Investigating magnetic properties of nanoparticles dispersed in a fluid is catching an increasing attention for their wide range of applications; however, a careful magnetic characterization requires low temperatures and vacuum conditions which represent a critical issue for a correct sample handling. In this paper, several experimental protocols to investigate low temperature magnetic properties of magnetic nanoparticles dispersed in fluid are described. In particular, by investigating interparticle interaction by remanence techniques at low temperature, some insight about particle aggregation in fluids has been given. © 2018 IEEE.

AB  - Magnetic nanoparticles (MNPs) are widely investigated due to their potential use in various applications, ranging from electronics to biomedical devices. The magnetic properties of MNPs are strongly dependent on their size and shape (i.e., morphology), thus appropriate tools to investigate their morphology are fundamental to understand the physics of these systems. Recently a new approach to study nanoparticle morphology by Transmission Electron Microscopy (TEM) analysis has been proposed, introducing the so-called Aspect Maps (AMs). In this paper, a further evolution of the AM method is presented, allowing determination of the nanoparticles 3D shape by TEM image. As a case study, this paper will focus on magnetite nanoparticles (Fe3O4), with a mean size of similar to 45 nm extracted from Magnetospirillum gryphiswaldense magnetostatic bacteria (MTB). The proposed approach gives a complete description of the nanoparticles morphology, allowing estimation of an average geometrical size and shape. In addition, preliminary investigation of the magnetic properties of MTB nanoparticles was performed, giving some insight into interparticle interactions and on the reversal mechanism of the magnetization.
