SQUID technique is extremely powerful to measure the moment versus applied magnetic field (e.g. hysteresis loops) or moment versus temperature curves of magnetic nanomaterials in a broad temperature range. Its sensitivity is very high, therefore a small amount of material is enough to ensure reliable signals. In addition to hysteresis loops, SQUID measurements also allow precise determination of the Curie, Néel or blocking temperatures of ferromagnetic, antiferromagnetic or superparamagnetic nanoparticles.
SQUID Magnetometry with DC & AC options, 7 Tesla maximum field and ultra low field capability is offered to explore static and dynamic magnetic properties of various samples including nanoparticles, thin films, bulk materials, even samples in liquid media at extended areas of temperatures (Low-T: 1.9 - 400 K) and (High-T: 300 - 800 K). SQUID is a state-of-art facility that probes the cooperative magnetism and evaluates the relative interactions.
