Magneto-Optical measurements of Hg1-XCdXTe alloys have provided a new means of studying impurities and defects in this important II-VI material. Two-photon magnetoabsorption TMPA has been used to accurately determine the temperature dependence of the energy gap of various HgCdTe alloys, revealing behavior that deviates from currently accepted models. In addition, magneto- optical techniques have been used to detect the presence of both shallow and deep impuritiesdefects and accurately determine their activation energies, thus providing information necessary for understanding the electrical and optical properties of the material.
