Imaging Local Effects of Voltage and Boron Doping on Spin Reversal in Antiferromagnetic Magnetoelectric Cr2O3 Thin Films and Devices
Adam Erickson, Syed Qamar Abbas Shah, Ather Mahmood +5
Chromia (Cr2O3) is a magnetoelectric oxide which permits voltage-control of the antiferromagnetic (AFM) order, but it suffers technological constraints due to its low Neel Temperat…
Post deposition interfacial Néel temperature tuning in magnetoelectric B:Cr2O3
Ather Mahmood, Jamie Weaver, Syed Qamar Abbas Shah +4
Boron (B) alloying transforms the magnetoelectric antiferromagnet Cr2O3 into a multifunctional single-phase material which enables electric field driven π/2 rotation of the Néel ve…
Search for magnetoelectric monopole response in CrO powder
Syed Q. A. Shah, Ather Mahmood, Arun Parthasarathy +1
Powder samples have been suggested as a pathway to fabricate isotropic magnetoelectric (ME) materials which effectively only have a pseudoscalar or monopole ME response. We demonst…
Nanoscale imaging of antiferromagnetic domains in epitaxial films of Cr2O3 via scanning diamond magnetic probe microscopy
Adam Erickson, Syed Qamar Abbas Shah, Ather Mahmood +4
We report direct imaging of boundary magnetization associated with antiferromagnetic domains in magnetoelectric epitaxial Cr2O3 thin films using diamond nitrogen vacancy microscopy…
Distance Dependence of the Energy Transfer Rate From a Single Semiconductor Nanostructure to Graphene
François Federspiel, Guillaume Froehlicher, Michel Nasilowski +9
The near-field Coulomb interaction between a nano-emitter and a graphene monolayer results in strong Förster-type resonant energy transfer and subsequent fluorescence quenching. He…
Circular dichroism of magneto-phonon resonance in doped graphene
P. Kossacki, C. Faugeras, M. Kühne +6
Polarization resolved, Raman scattering response due to E phonon in monolayer graphene has been investigated in magnetic fields up to 29 T. The hybridization of the E…
Probing the band structure of quadri-layer graphene with magneto-phonon resonance
C. Faugeras, P Kossacki, A. A. L. Nicolet +4
We show how the magneto-phonon resonance, particularly pronounced in sp2 carbon allotropes, can be used as a tool to probe the band structure of multilayer graphene specimens. Even…
Epitaxial graphene morphologies probed by weak (anti)-localization
Ather Mahmood, Cécile Naud, Clément Bouvier +6
We show how the weak field magneto-conductance can be used as a tool to characterize epitaxial graphene samples grown from the C or the Si face of Silicon Carbide, with mobilities…
Quasiparticle scattering off phase boundaries in epitaxial graphene
A. Mahmood, P. Mallet, J. -Y. Veuillen
We investigate the electronic structure of terraces of single layer graphene (SLG) by scanning tunneling microscopy (STM) on samples grown by thermal decomposition of 6H-SiC(0001)…
Production, properties and potential of graphene
Caterina Soldano, Ather Mahmood, Erik Dujardin
This review on graphene, a one atom thick, two-dimensional sheet of carbon atoms, starts with a general description of the graphene electronic structure as well as a basic experime…
Side-gated transport in FIB-fabricated multilayered graphene nanoribbons
Jean-Francois Dayen, Ather Mahmood, Dmitry S. Golubev +3
In this Letter, we present the patterning, exfoliation and micromanipulation of thin graphitic discs which are subsequently connected and patterned into sub-100nm wide ribbons with…
