Provision of a Magneto Optical Kerr Effect (MOKE) Microscope

The National Physical Laboratory [NPL] requirement is for a magneto optical Kerr effect [MOKE] microscope for imaging magnetic domains in the surface of solid samples. The purpose of this system is to connect macro and nano scale characterization. The system needs to be able to achieve a resolution down to 300 nm and total sample size of a few mm. Capturing speed should allow for studying dynamic processes where images need to be taken with a repetition rate of up to 200 kHz. This is necessary in order to characterize the behaviour of magnetic thin films, magnetic nanostructures, and novel 2D materials exhibiting magnetic properties, which are objects of study within the Quantum group and whose dynamic behaviour is not accessible with the current instrumentation.
