Abstract: Provided are an atomic magnetometer and an operating method of the same. The atomic magnetometer includes a vapor cell receiving a circularly polarized pump beam and a linearly polarized probe beam and containing an alkali metal vapor, a detector adapted to receive the probe beam passing through the vapor cell to measure magneto-optical rotation of the probe beam, a feedback coil to establish a negative feedback magnetic field signal orthogonal to a first plane defined by traveling directions of the probe beam and the pump beam and provide the negative feedback magnetic field signal to the vapor cell, and a feedback amplifier adapted to provide feedback current to the feedback coil such that the negative feedback magnetic field proportional to a measurement magnetic field is established. The measurement magnetic field of a measurement target provides magneto-optical rotation of the probe beam in the vapor cell.

Abstract: A method of controlling a magnetization state using an imprinting technique may be provided. The method may include moving first and second magnetic structures, which have different magnetization states, toward each other and changing a magnetization state of the first or second magnetic structure, when a distance between the first and second magnetic structures is reduced. A magnetic field, which is produced by a magnetization state of one of the first and second magnetic structures, may be used to align a magnetization state of the other, when the magnetization state of the first or second magnetic structure is changed.
