Abstract: The influence of Coulomb correlation on magnetic and spectral properties in metallic rutile phase of vanadium dioxide is studied by state of the art LDA+DMFT method. Calculation results in strongly correlated metallic state with an effective mass renormalization

m^{*} / m \approx 2

$m^*/m\approx2$ . Uniform magnetic susceptibility shows Curie-Weiss temperature dependence with effective magnetic moment,

p_{e f f}^{t h e o r} = 1.54 μ_{B}

$p_{\rm eff}^{\rm theor}=1.54\mu_B$ , in a good agreement with the experimental value

p_{e f f}^{\exp} = 1.53 μ_{B}

$p_{\rm eff}^{\exp}=1.53\mu_B$ that is close to ideal value for V

^{4 +}

$^{4+}$ ion with the spin

S = 1 / 2

$S=1/2$ ,

p_{e f f} = 1.73 μ_{B}

$p_{eff} = 1.73 \mu_B$ . Calculated spectral function shows well developed Hubbard bands observable in the recent experimental photoemission spectra. We conclude that VO

_{2}

$_2$ in rutile phase is strongly correlated metal with local magnetic moments formed by vanadium

$d$ -electrons.
