We present a detailed study of local and non-local correlations in theelectronic structure of elemental transition metals carried out by means of theQuasiparticle Self-consistent GW (QSGW ) and Dynamical Mean Field Theory(DMFT). Recent high resolution ARPES and Haas-van Alphen data of two typicaltransition metal systems (Fe and Ni) are used as case study. (i) We find thatthe properties of Fe are very well described by QSGW. Agreement with cyclotronand very clean ARPES measurements is excellent, provided that final-statescattering is taken into account. This establishes the exceptional reliabilityof QSGW also in metallic systems. (ii) Nonetheless QSGW alone is not able toprovide an adequate description of the Ni ARPES data due to strong local spinfluctuations. We surmount this deficiency by combining nonlocal chargefluctuations in QSGW with local spin fluctuations in DMFT (QSGW + 'MagneticDMFT'). (iii) Finally we show that the dynamics of the local fluctuations areactually not crucial. The addition of an external static field can lead tosimilarly good results if non-local correlations are included through QSGW.
