probing Electron Spin Resonance in monolayer graphene
Physical Review Letters, 2017Co-Authors: Timothy J Lyon, Jonas Sichau, August Dorn, A Centeno, Amaia Pesquera, A Zurutuza, Robert H BlickAbstract:The precise value of the g factor in graphene is of fundamental interest for all Spin-related properties and their application. We investigate monolayer graphene on a Si/SiO_{2} substrate by resistively detected Electron Spin Resonance. Surprisingly, the magnetic moment and corresponding g factor of 1.952±0.002 is insensitive to charge carrier type, concentration, and mobility.

conduction Electron Spin Resonance of small silver particles
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2006Co-Authors: Marek Danilczuk, Jaroslaw Sadlo, Anders Lund, Hirohisa Yamada, Jacek MichalikAbstract:Electron Spin Resonance (ESR) spectroscopy has been used to study the conduction Electron Spin Resonance (CESR) of small silver particles stabilized in dehydrated Ag-rho zeolite. Silver particles were produced by hydrogen reduction at elevated temperatures and diameter of the stabilized particles was calculated based on the linewidth of CESR signal using Kawabata theory. © 2005 Elsevier B.V.

Observation of conduction Electron Spin Resonance in boron doped diamond
Physical Review B: Condensed Matter and Materials Physics, 2013Co-Authors: Peter Szirmai, Gabor Fabian, Balint Nafradi, T Pichler, László Forró, Christopher Bauerle, Soumen Mandal, János Koltai, Oliver Aneurin Williams, Ferenc SimonAbstract:We observe the Electron Spin Resonance of conduction Electrons in boron doped (6400 ppm) superconducting diamond (Tc =3.8 K). We clearly identify the benchmarks of conduction Electron Spin Resonance (CESR): the nearly temperature independent ESR signal intensity and its magnitude which is in good agreement with that expected from the density of states through the Pauli Spin-susceptibility. The temperature dependent CESR linewidth weakly increases with increasing temperature which can be understood in the framework of the Elliott-Yafet theory of Spin-relaxation. An anomalous and yet unexplained relation is observed between the g-factor, CESR linewidth, and the resistivity using the empirical Elliott-Yafet relation.

Electron Spin dynamics and Electron Spin Resonance in graphene
EPL, 2010Co-Authors: Balázs Dóra, F. Murányi, Ferenc SimonAbstract:A theory of Spin relaxation in graphene including intrinsic, Bychkov-Rashba, and ripple Spin-orbit coupling is presented. We find from Spin relaxation data by Tombros et al. (Nature, 448 (2007) 571) that intrinsic Spin-orbit coupling dominates over other contributions with a coupling constant of 3.7 meV. Although it is 1–3 orders of magnitude larger than those obtained from first principles, we show that comparable values are found for other honeycomb systems, MgB2 and LiC6; the latter is studied herein by Electron Spin Resonance (ESR). We assess the feasibility of bulk Electron Spin Resonance spectroscopy on graphene and identify experimental conditions where such experiments are realizable.
