The magnetic moment and lifetime of the 19/${2}^{\mathrm{\ensuremath{-}}}$, 4.367 MeV state in $^{49}\mathrm{Cr}$ have been measured in a transient magnetic field experiment. The nuclei were excited in the $^{12}\mathrm{C}$${(}^{40}$Ca,2pn${)}^{49}$Cr reaction and recoiled in a thick polarized gadolinium foil. The field strength was calibrated by a simultaneous g-factor measurement of excited states in $^{50}\mathrm{Cr}$ and $^{46}\mathrm{Ti}$. The mean lieftime, found from Doppler-shifted line-shape analysis, is \ensuremath{\tau}(19/${2}^{\mathrm{\ensuremath{-}}}$)=2.7(2) ps and the g factor is g=+0.78(12). The g value implies a substantial ${\mathit{f}}_{7/2}$ proton contribution to the total spin of this state and the result is discussed in terms of both the shell model and the cranked shell model.
