    Abstract: An apparatus for measuring the magneto-optical Kerr effect (MOKE) of a specimen requiring analysis of magnetic properties, such as a magnetic random access memory (MRAM) or electrical steel sheet, is disclosed. The disclosed MOKE measuring device includes a rotational chuck on which a MOKE measurement target is disposed and which rotates the MOKE measurement target, a first magnetic field generator including a first coil spaced apart from the rotational chuck and tilted at a predetermined angle with respect to the rotational chuck, and configured to generate a magnetic field, a second magnetic field generator including a second coil spaced apart from the rotational chuck and tilted at a predetermined angle with respect to the rotational chuck, and configured to generate a magnetic field, and a frame to which the first and second magnetic field generators are fixed.
