Fabrication of nanomechanical resonator with non-local spin valve structure for spin detection and control

摘要

We have fabricated ultra-sensitive nanomechanical resonators with an integrated non-local spin valve structure. The obtained sensitivity is 1.42 × 10-17 N for the flexural mode and 1.68 × 10-18 N for the torsional mode, which indicates that the resonator is able to detect spin relaxation in terms of torque measurements.
