CryoBIND AC susceptibillity systems
How do we know about sensitivity? Here is how:
In order to achieve the highest level of sensitivity and to get rid of the coil-misbalance offset voltages a special hardware has been used and integrated into the measuring system (Model T).
Owing to improved signal-to-noise performances this measuring system reaches the sensitivity level (expressed in equivalent magnetic moment, defined as Δm= Δχ • Hac• V, Δχ is susceptibility resolution of the apparatus, Hac primary field and V volume of the sample) better than 2 nanoEMU.
We illustrate hereby the measurements on small Nb platelet performed with the latter sensitivity.
