ESR-STM : from continuous-wave to pulsed mode
ESR-STM is an emerging technique that enables spin-resonance detection of single spins.
The principle of this method consists in measuring the spin-polarized tunnel current as function of the frequency of a microwave signal (DC- 40 GHz) irradiating the sample.
In this talk, I will first describe the working principles of ESR-STM used in the continuous mode and its application to measurements of the magnetic spectrum of magnetic molecules(FePc) deposited on Ag(100)/MgO(100).
Second, I will show that ESR-STM can also be used in the pulsed mode, enabling single spin manipulation.
I will show that best results are obtained by designing sequences combining microwave pulses and tip-bias pulses.
