Roger F. Harrington and the Method of Moments: Part 2: Electrodynamics

The method of moments (MOM), as introduced by Roger F. Harrington more than 50 years ago, is reviewed in the context of the classic potential integral equation (IE) formulations applied to both electrostatic (part 1) and electrodynamic or full-wave problem ...

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 ...

Kapellasite: A Kagome Quantum Spin Liquid with Competing Interactions

Magnetic susceptibility, NMR, muon spin relaxation, and inelastic neutron scattering measurements show that kapellasite, Cu3Zn(OH)(6)Cl-2, a geometrically frustrated spin-1/2 kagome antiferromagnet polymorphic with herbertsmithite, is a gapless spin liquid ...

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

Violetta Sessi

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, Markus Etzkorn, Géraud Moulas

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

Clotaire Michel

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 ...

Observation of Two Nondispersive Magnetic Excitations in NiO by Resonant Inelastic Soft-X-Ray Scattering

Marco Grioni, Helmuth Berger, Thorsten Schmitt, Xiaoqiang Wang, Xiao Wang

We present high resolution (Delta E=120 meV) resonant inelastic x-ray scattering data measured at the Ni L-3 edge (2p(3/2)-> 3d) on the paradigmatic antiferromagnetic oxide NiO. Spectra reveal clear signatures of magnetic excitations at similar to 95 and 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 ...

Electronic structure of pyrochlore Cd2Re2O7

Helmuth Berger

Detailed band structure calculations have been performed for Cd2Re2O7 in high-, middle- and low-temperature (T) phases. The calculations are based on the observed lattice structures from x-ray diffraction measurements. The spin-orbit interaction is incorpo ...

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 ...
