As is well known a linearly polarized resonant laser will cause atoms to generate a magnetic tensor moment(MTM)by polarizing them. When there exists an external magnetic field, it is possible that the moment will precess around the field. In the presence of a radio frequency(RF) exciting source, we investigate theoretically the dependence of time-independent(direct current, DC), the first and second harmonic signal of the MTM precession on magnetic vector field, and obtain its analytical solution by solving...
