Fig. 3 — Magnetorelaxometry principle. The top line (from left to right) portrays a nanoparticle ensemble‘s behavior: initially in a disordered state without magnetization, partly rotated towards the field direction during magnetizing, and turning back into a randomly oriented distribution of magnetic moments leading to the detected magnetization relaxation. Typically a field of about 1.5 mT is applied for 1 s. After removal of the field and a short interval the SQUID amplifier needs to recover, the relaxation signals are acquired for 0.5 s.
