Abstract:

We have performed magnetorelaxometry measurements on superparamagnetic magnetite (Fe3O4) nanoparticles using a low-cost custom-made Giant MagnetoImpendance magnetometer. We demonstrate that we are able to evaluate the concentration of nanoparticles in the sample (with a volume of around 150 l) by comparison with reference measurements of the induced magnetic field using fits to the NĂ©el expression for magnetorelaxation.
