Controlling the tunneling anisotropic magnetoresistance (TAMR). a and b Calculated lm-decomposed partial density of states (PDOS) of the dxy, dπ, and \(d_{z^2} \) bands of the Fe atom with a magnetization vector in the plane of the molecule a and in the direction of the applied magnetic field, perpendicular to the plane of the molecule b. The insets show the direction of the magnetic moment schematically. The energy is given with respect to EF. Black lines represent the energy of the molecular orbital closest to EF. c and d Band-decomposed charge density plots for the molecular orbitals close to EF, showing the similar spatial distribution of the Kondo resonance as in Fig. 3a, d. We note that the orbital density on the C atoms in c is unlikely to have a significant overlap with the substrate and thus will not contribute significantly to the signals in the dI/dV maps. e TAMR values at different bias voltages calculated from the dI/dV spectra taken on the Fe center at B = 0 and 11 T. f TAMR values at different magnetic field calculated from the dI/dV spectra taken on the Fe center at the bias voltage of −1.06 mV. a.u. arbitrary units
