Mechanical dissipation from charge and spin transitions in oxygen-deficient SrTiO3 surfaces
Mechanical dissipation from charge and spin transitions in oxygen-deficient SrTiO3 surfaces
Bodies in relative motion separated by a gap of a few nanometers can experience a tiny friction force. This non-contact dissipation can have various origins and can be successfully measured by a sensitive pendulum atomic force microscope tip oscillating laterally above the surface. Here, we report on the observation of …
