This module focuses on the important role of a STM tip in actual ESR measurements. We introduce the detecting mechanism of a spin-polarized tip in ESR measurements; the common procedures to prepare an ESR tip in an STM system; and how to estimate the spin-polarization of the tip from differential conductance spectra. We also talk about the physical model of tip magnetic field in a STM junction and highlight the newly developed tip-field sweep ESR measurements by comparing with the conventional frequency sweep ESR measurements.

Please note that the voltages in this tutorial are referenced to tip bias.

I think the current-sweep ESR very cool! Can I know which paper is it from?
