Direct observation of interfacial exchange coupling in a magnetic tunnel junction through spin-polarized quasiparticle interference
SP-STM and quasiparticle interference show Fe tip induces up to 10 meV shift in Cr(001) spin-polarized surface state, tunable by distance and magnetic field, indicating exchange coupling mediated by 2D states.
