d-Orbital directed photoemission from manganese fluoride single crystals using AlKα radiation

Abstract

Angle-resolved photoemission energy distributions (PEDs) were obtained from valence bands of MnF₂ single crystals using AlK_α radiation. A pronounced variation in the PEDs was observed as the electron take-off angle was varied relative to the crystalline axes, for the (111) crystal face. The observed variation is attributed to the t_2g and e_g symmetry properties of the manganese 3d initial state wavefunctions and is well described by an angle-dependent transition-matrix model. The results are in good agreement with the multi-configurational Hartree–Fock calculations of Viinikka and Bagus.
