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.

Abstract
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.
