Valence Orbitals Driving the Spin Dynamics in a Rare-Earth Single-Atom Magnet

Harald Brune, François Patthey, Stefano Rusponi, Marina Pivetta, Dante Philippe Sblendorio

We combine spin-polarized scanning tunneling microscopy with quantum master equation analysis to investigate the spin dynamics of the single atom magnet Dy on graphene/Ir(111). By performing reading and writing experiments, we show that the strongly spin p ...

Resolving the spin splitting in the conduction band of monolayer MoS2

Andras Kis, Ahmet Avsar, Kolyo Marinov

Time-reversal symmetry and broken spin degeneracy enable the exploration of spin and valley quantum degrees of freedom in monolayer transition-metal dichalcogenides. While the strength of the large spin splitting in the valance band of these materials is n ...

Electrical and Magnetical Modeling of Inductive Coupled Power Transfer Systems

Christophe Bruno Auvigne

Nowadays, there is a very high number of electronic devices with different ranges of power. Desktop peripherals and cellphones are an example of widely used low power devices. Contactless power transfer is useful to supply or recharge these devices without ...

Tuning the g-factor of neutral and charged excitons confined to self-assembled (Al,Ga)As shell quantum dots

Anna Fontcuberta i Morral, Martin Heiss, Eleonora Russo, Pierre Michel Corfdir, Yannik Fontana

We study the neutral exciton (X) and charged exciton (CX) transitions from (Al,Ga) As shell quantum dots located in core-shell nanowires, in the presence of a magnetic field. The g-factors and the diamagnetic coefficients of both the X and the CX depend on ...

Observation of conduction electron spin resonance in boron-doped diamond

László Forró, Bálint Náfrádi, Péter Szirmai, Ferenc Simon

We observe the electron spin resonance of conduction electrons in boron-doped (6400 ppm) superconducting diamond (T-c = 3.8 K). We clearly identify the benchmarks of conduction electron spin resonance (CESR): the nearly temperature independent electron spi ...

Influence of disorder on electrically and optically detected electron spin nutation

A numerical study of the influence of disorder in semiconductors on spin-Rabi nutation observed with pulsed electrically or optically detected magnetic-resonance techniques (pEDMR and pODMR, respectively) is presented. It is shown that transient nutation s ...

Identifying the electron spin resonance of conduction electrons in alkali doped SWCNTs

László Forró, Luka Ciric

We study the electron spin resonance (ESR) signal of pristine and potassium doped SWCNTs. We identify signals of a superparamagnetic background, a low intensity impurity, and of the conduction electron spin resonance (CESR). The latter only appears upon th ...

Dimer phases in quantum antiferromagnets with orbital degeneracy

Dmitri Ivanov

We study and solve the ground-state problem of a microscopic model for a family of orbitally degenerate quantum magnets. The orbital degrees of freedom are assumed to have a directional character and are represented by static Potts-like variables. In the l ...

Transport and recombination in organic light-emitting diodes studied by electrically detected magnetic resonance

Frank Nüesch, Libero Zuppiroli

We have used electrically detected magnetic resonance (EDMR) to study a series of multilayer organic devices based on aluminum (III) 8-hydroxyquinoline (Alq3). These devices were designed to identify the microscopic origin of different spin-depe ...
