Characterization of the Magnetic Properties of Pyrogel*

During the design and construction of a furnace for materials processing in high magnetic fields being built to operate in the 89 mm, room-temperature bore of a 9.4 Tesla superconducting magnet [1], the aerogel-based insulating material known as Pyrogel® [2] was located. To provide magnetic "fingerprints" of the material, the first step was to use a commercial magnetometer to study the temperature dependence of the low magnetic field (0.1 Tesla) susceptibility from 2 K to 300 K and the magnetic field dependence of the isothermal (5 K) magnetization up to 7 Tesla. The analysis of these data will be presented with the goal of making the results available via FAIR data management practices [3]. Extensions of the work to explore the high temperature (> 300 K) properties may be presented.
