Excited states in ${}^{52}\mathrm{Fe}$ have been studied up to spin $10\ensuremath{\Elzxh}$ in the reaction ${}^{28}\mathrm{Si}{+}^{28}\mathrm{Si}$ at 115 MeV beam energy by using in-beam $\ensuremath{\gamma}$-ray spectroscopy methods at the GASP array. The excitation energy of the yrast ${10}^{+}$ state is 7.381 MeV, almost 0.5 MeV above the well known ${\ensuremath{\beta}}^{+}$-decaying yrast ${12}^{+}$ state. Experimental upper limits for the $B(E4)$ transition probabilities from the ${12}^{+}$ isomer to the ${8}_{1}^{+}$ and ${8}_{2}^{+}$ states have been determined. The mean lifetimes of five excited states have been measured by using the Doppler shift attenuation method. Complete diagonalizations in the $\mathrm{pf}$ major shell lead to very good agreement with the experimental level scheme and transition probabilities. The lifetime, $\mathrm{log}\mathrm{ft}$ value, branching ratios, and $B(E4)$ values are calculated for the ${12}^{+}$ isomer. The positive parity states are also interpreted in terms of a Nilsson projected method. The structure of the yrast levels of ${}^{52}\mathrm{Fe}$ is compared with those of its cross conjugate ${}^{44}\mathrm{Ti}.$
