Electron spin resonance of single iron phthalocyanine molecules and role of their non-localized spins in magnetic interactions

Electron spin resonance spectroscopy has traditionally been used to study large ensembles of spins, but its combination with scanning tunnelling microscopy recently enabled measurements on single adatoms. Now, individual iron phthalocyanine complexes adsor ...

Quantum dynamics in individual surface spins

Tobias Bilgeri

This thesis presents a combined experimental and theoretical study of the classical and quantum magnetization dynamics in single magnetic adatoms and molecules, and on the classical and quantum coherent control thereof. First, a detailed description of t ...

Upgrade of a low-temperature scanning tunneling microscope for electron-spin resonance

Harald Brune, François Patthey, Nicolas Weiss, Donat Fabian Natterer, Tobias Bilgeri, Patrick Robert Forrester

Electron spin resonance with a scanning tunneling microscope (ESR-STM) combines the high energy resolution of spin resonance spectroscopy with the atomic scale control and spatial resolution of STM. Here we describe the upgrade of a helium-3 STM with a 2D ...

Antiferromagnetic MnNi tips for spin-polarized scanning probe microscopy

Harald Brune, François Patthey, Donat Fabian Natterer, Tobias Bilgeri, Patrick Robert Forrester

Spin-polarized scanning tunneling microscopy (SP-STM) measures magnetoresistance with atomic resolution. While various methods for achieving SP probes have been developed, each is limited with respect to fabrication, performance, and operating conditions. ...
