The spectrum of a single molecular electron spin qubit — •Tim Dierker1, Dinesh Pinto2,3, and Wolfgang Harneit11University of Osnabrück — 2Max Planck Institute for Solid State Research, Stuttgart — 3Institut de Physique, École Polytechnique Fédérale de Lausanne

A single-spin electron paramagnetic resonance (EPR) measurement of N@C60 within a C60 matrix using a single near surface nitrogen vacancy (NV) center was realized at low temperatures. Utilizing optically detected magnetic resonance (ODMR) a double electron-electron resonance (DEER) spectrum was obtained, showing a hyperfine structure reminiscent of N@C60 but slightly distorted [1]. The features of the measured spectrum are compared to theoretical calculations resulting from second order perturbation theory. Here especially the possibilities for asymmetric splitting are investigated for zero-field splitting and non-isotropic hyperfine effects containing orientational dependencies.
