We have developed a magnetic-field-type scanning near-field optical microscopy (SNOM) system, which enables us to obtain two-dimensional near-field images under magnetic fields up to 4 T. We have performed two-dimensional near-field scanning optical spectroscopy on (Cd,Mn)Te self-assembled quantum dots with this system.
Key words: scanning near-field optical microscopy (SNOM), magnetic field, self-assembled quantum dots, photoluminescence, dilute magnetic semiconductor
