Construction of an optical and magneto-optical diffractometer for studies of patterned magnets
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
A MOKE setup was constructed and measurements have been performed in order to verify the versatility of this equipment. The quadrupole air core coils are capable of delivering a maximum magnetic field of 13 mT in longitudinal, transversal as well as polar MOKE. The diffractometer enables reflective scans (Kerr effect) from 20 to 90 degrees and transmissive scans (Faraday effect) from 0 to 90 degrees (optical convention). The combined equipment that constitutes of these two parts enables thorough characterization of optical, magnetical and magneto-optical phenomena which will be of great benefit for studies of patterned nano-magnets. The setup is designed to reveal the influence of optical effects coupled to various structures like plasmon resonances and plasmonic band gaps into the magnetic and magneto-optical properties of patterned nanostructures.
