The report describes a high frequency paramagnetic resonance spectrometer which was designed to operate at frequencies as high as 350 GHz, and its application to a number of specific material investigations. The spectrometer was designed and built during the initial year of this contract, and was applied initially in the study of CaF2 - Dy2. It was subsequently employed in studying the zero field split levels of TiO2 - Mn3, ZnWO4 - Ni2 and in attempts to observe and measure the zero field splitting of Fe3 in the hemoglobin molecule. This latter attempt has so far proven completely unsuccessful indicating that the splitting is considerably greater than 10cm. Plans have also been formulated to utilize the spectrometer in studies of exchange and arisotropy effects in ferromagnetic, antiferromagnetic and ferrimagnetic materials where high frequency microwave studies may lead to a more complete understanding of these interactions.
