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 ...

Anisotropy of transport in bulk Rashba metals

Claudio Grimaldi

The recent experimental discovery of three-dimensional (3D) materials hosting a strong Rashba spin-orbit coupling calls for the theoretical investigation of their transport properties. Here we study the zero-temperature dc conductivity of a 3D Rashba metal ...

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 ...

Coordination dependent magnetic properties of 3d and 4d metal nano-structures

In this thesis, the magnetic properties of self-assembled 3d and 4d metal nano-structures supported on surfaces have been investigated. The atomic coordination within the nano-structures was found to profoundly affect important quantities such as the magne ...

Magnetocrystalline anisotropy energy of Co and Fe adatoms on the (111) surfaces of Pd and Rh

Harald Brune, Stefano Rusponi, Pietro Gambardella, Anne Lehnert

We performed a combined theoretical and experimental investigation of the orbital magnetism and magnetocrystalline anisotropy of isolated Co and Fe adatoms on Pd(111) and Rh(111). Theoretical calculations of the spin and orbital moments are based on ab ini ...

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 ...
