Optical Addressing of Quantum States in Single-Molecule Magnets
Single-molecule magnets (SMMs) exhibit nanometric size and long magnetic relaxation times which can reach timescales of months at low temperatures. These fascinating properties make them interesting candidates for future data storage and computational devices.
Single-molecule magnets (SMMs) exhibit long magnetic relaxation times which can reach timescales of months at low temperatures, without the presence of magnetic long-range order. SMMs with a single lanthanide ion acting as a magnetic center possess extremely narrow optical transitions, which allow to access the individual magnetic quantum states by resonant laser light. In this master project the low-temperature magneto-optical properties of several lanthanide-containing SMMs shall be investigated in the near infrared regime using an external cavity scanning diode laser.
