Sublattice ferrimagnetism in quasifreestanding graphene

AG Rybkin, AV Tarasov, AA Rybkina, DY Usachov… - Physical Review Letters, 2022 - APS
We show that graphene can be magnetized by coupling to a ferromagnetic Co film through a
Au monolayer. The presence of dislocation loops under graphene leads to a ferrimagnetic …

Proximity-induced spin-orbit effects in graphene on Au

A López, L Colmenárez, M Peralta, F Mireles, E Medina - Physical Review B, 2019 - APS
We introduce apz-d coupling model Hamiltonian for the π-graphene/Au bands that predicts
a rather large intrinsic spin-orbit (SO) coupling as is being reported in recent experiments …

Proximity-induced exchange and spin-orbit effects in graphene on Ni and Co

M Peralta, E Medina, F Mireles - Physical Review B, 2019 - APS
The proximity-induced effects of the nearly commensurate lattice structure of a graphene
