  The present work reports the preparation of polycrystalline multiferroic
$GdFeO_3$ (GdFO) and characterization with x-ray diffraction (XRD),
magnetization, temperature dependent Raman spectroscopy, temperature and
magnetic field dependent $^{57}Fe$ M$\ddot{o}$ssbauer spectroscopy
measurements. The sample is found to be phase pure from Rietveld refinement of
XRD pattern. The M$\ddot{o}$ssbauer spectra measured in the presence of
external magnetic field show the signatures of field induced spin reorientation
transition, which are corroborated by magnetization measurements. From the
temperature dependent variation of internal hyperfine field, N$\grave{e}$el
transition temperature ($T_{N,Fe}$) of 672.5$\pm$0.2 K and critical exponent
($\beta$) of 0.333$\pm$0.003 is obtained. Temperature dependent (300 - 760 K)
Raman spectroscopy measurements show the signatures of spin-phonon coupling and
local structural re-arrangement across $T_{N,Fe}$.
