  • Patent number: 11906604
    Abstract: An apparatus to detect and measure a T-MOKE signal includes a first linear polarizer located on the optical path between a light source and a reflecting surface of a sample, a device to produce a magnetic field at the sample location, the device being configured to direct the magnetization perpendicularly to the optical plane of incidence and to reverse the direction of the magnetic field, a rotatable quarter-wave plate located after the reflecting surface on the optical path of the reflected light, a second linear polarizer that is rotatable and is located after the quarter-wave plate on the optical path of the reflected light, and a photo-detector located after the second linear polarizer on the optical path of the reflected light, the photo-detector being configured to measure the intensity of the light. A method for extracting a T-MOKE signal in an ellipsometric measurement procedure employs such an apparatus.
