Abstract
The polarization of light emitted during inelastic tunneling of electr ons into both Au(111) and Fe(001) using W(111) tips in an STM junction has been fully characterized by measuring the Stokes parameters. The emitted light for both Au(111) and Fe(001) is fully polarized; it is p redominantly linearly polarized in the plane formed by the tip axis an d direction of light emission. For both samples, there is a small circ ular polarization which is tip-dependent and can be attributed to tip asymmetries. No magnetization-dependent circular polarization was obse rved for Fe(001).
