For the study of astronomical refraction he developed an unusual method of calculating the vertical gradient of air temperature together with his Assistent Felix Hausdorff.
Other stresses may be as a result of moulding pressures, extrusion orientation, thermal gradients during solidification and externally imparted stresses.

The compound was first obtained by Martha Greenblatt and others by a temperature gradient flux technique.
B. A. Finlayson first explained in 1970 (in his paper "Convective instability of ferromagnetic fluids", Journal of Fluid Mechanics 40:753-767) how an external magnetic field imposed on a ferrofluid with varying magnetic susceptibility, e.g., due to a temperature gradient, results in a nonuniform magnetic body force, which leads to thermomagnetic convection.
