Mo¨ssbauer’s discovery and its application has opened a new microscopic method to study in the condensed matter field. The Mo¨ssbauer resonance line is extremely narrow and allows hyperfine interaction to be resolved and evaluated in a straightforward way. In this paper, Mo¨ssbauer effect and spectroscopy are descrived and the current status of applications to the condensed matter physics such as Fe(OH)₃& Fe₂O₃are reviewed. The isomer shift of Fe ion in Fe(OH)₃is 0.189mn/sec and 0.221mn/sec to Fe₂O₃. The quadrupole splitting of these absorbers were also measured as 0.741mm/sec and -0.072mm/sec respectively. Using the hyperfine splitting of Fe₂O₃, we are able to account that the internal magnetic field at the position of Fe, is 514.92Koe.
