Plasmon rulers are an emerging concept in which the strong near-field coupling of plasmon nanoantenna elements is employed to Obtain structural information at the nanoscale. Here, we combine nanoplasmonics and nano-magnetism to conceptualize a magnetoplasmonic dimer nanoantenna that would be able to report nanoscale distances While optimizing its own spatial orientation. The latter constitutes an active operation in which a dynamically optimized optical response per measured unit length allows for the measurement of small and large nanoscale distances With about 2 orders of magnitude higher precision than current state-of-the-art plasmon rulers. We further propose,a concept to Optically measure the nanoscale response to the controlled application of force with a magnetic field.
