Magneto Kerr Effect
The magneto-optical Kerr effect is a phenomenon in which the polarisation of light reflected from a magnetic material changes in response to an applied magnetic field. This effect occurs due to the interaction between the magnetic properties of the material and the incident light. When a magnetic field is applied to the material, it alters the way light is reflected, leading to changes in the polarisation of the reflected light. The Magneto Kerr Effect is widely used in materials science and condensed matter physics to study magnetic properties, such as magnetisation direction and strength, of various materials. It has applications in magnetic storage devices, magnetic sensors, and research tools for understanding the behavior of magnetic materials at the atomic level.
