${\mathrm{Fe}}_2\mathrm{P}$ alloys have been identified as promising candidates for magnetic refrigeration at room-temperature and for custom magnetostatic applications. The intent of this study is to accurately characterize the magnetic ground state of the parent compound, ${\mathrm{Fe}}_2\mathrm{P}$, with two spectroscopic techniques, $\mu \mathrm{SR}$ and NMR, in order to provide solid bases for further experimental analysis of ${\mathrm{Fe}}_2\mathrm{P}$-type transition metal based alloys. We perform zero applied field measurements using both techniques below the ferromagnetic transition $T_C=220$ K. The experimental results are reproduced and interpreted using first principles simulations, validating this approach for quantitative estimates in alloys of interest for technological applications.
