Static Magnetic Properties of Cryogel${}^{\mathrm{\circledR }}$ and Pyrogel${}^{\mathrm{\circledR }}$ at Low Temperatures and in High Magnetic Fields

The static magnetic properties of the silica-based aergoels of Cryogel${}^{\mathrm{\circledR }}$ and Pyrogel${}^{\mathrm{\circledR }}$, manufactured by Aspen Aerogels${}^{\mathrm{\circledR }}$, were measured over a range of temperatures (2 K $\le$ T $\le$ 400 K) and in magnetic fields up to 70 kG. These data and a model of the responses are reported so these properties are familiar to others who may benefit from knowing them before the materials are employed in potential applications.
