A new thermogyromagnetic effect has been detected and studied experimentally with the help of a sensitive SQUID magnetometer. The effect can be summarized by saying that a metal cylinder, in which a radial temperature gradient VT has been set up, becomes magnetized when it is rotated at a frequency Ω. The magnetic flux associated with the cylinder is Φ = AVTil, where Д — 2Х ΚΓ¹ Φο-s-cm/deg. In a sense, this effect can be thought of as an analog of the Nernst-Ettinghausen effect. The latter effect is the onset of an electric current in a metal object in which gradients of the temperature and the magnetic field are set up in perpendicular directions.
