- Abstract
- Assemblies of highly ordered magnetic nanoparticles dominated by dipolar particle coupling are analyzed in respect to their capability to act as a magnetic field sensor. We demonstrate a wide range of possibilities to tailor the response properties of the sensor to specific demands by either modification of the nanocomponents or the structure as a whole. Additionally, we find that increased detection sensitivity may be bought at the cost of an inherent noise signal. This behavior is contributed to the existence of four distinct operation modes each governed by a different energy contribution within the assembly.
