Originally designed for use with pressure cells on an MPMS3 magnetometer, SquidLab is a modular object-oriented platform implemented in Matlab with a range of importers for different widely-available magnetometer systems and has been tested with a broad variety of background and signal types. The software allows background subtraction of baseline signals, signal preprocessing, and performing fits to dipole data. A plugin system allows users to easily extend the built-in functionality with their own importers, processes or fitting algorithms.
With over 500 downloads already to a rich variety of labs worldwide - SquidLab is proving an indispensible tool for high-pressure magnetic measurements and a whole host of other applications.
