Thermomagnetic Torque in NH3

Abstract

A study of the thermomagnetic torque (Scott effect) in N${\mathrm{H}}_3$ is reported. The small positive Scott torque is measured as a function of magnetic field for absolute pressures of 0.028, 0.043, 0.048, 0.057, and 0.078 Torr. At maximum torque, the magnetic field $H_0$ for each pressure $P$ is given by $H_0=b(P+a)\mathrm{}$, where $a=-4.4\mathrm{}\times {10}^{-3\mathrm{}}$ Torr and $b=3.18\mathrm{}\times {10}^3$ Oe/Torr.
