High frequency atomic magnetometer by use of electromagnetically induced transparency.
Atomic magnetometers have achieved magnetic sensitivities in the subfemtotesla regime. Their bandwidth is determined by the transverse spin relaxation rate, 1/T2, which also determines the magnetic sensitivity. It is theoretically demonstrated that by using an electromagnetically induced transparent probe beam in a pump-probe atomic magnetometer, it is possible to operate the latter at frequencies much higher than its bandwidth, maintaining a high signal-to-noise ratio.
