Abstract: Members of a particular class of magnetic garnet compositions show characteristics useful for incorporation in magnetic memory devices which depend for their operation on the positioning of single wall domains (''''bubbles''''). Such compositions ordinarily in the form of a supported layer are noteworthy for high bubble mobility and small temperature dependence of magnetic properties affecting operation. These compositions include silicon and/or germanium as a partial replacement for iron.

Abstract: Large single crystals of lead molybdate of high optical quality are grown by pulling from a melt under conditions of low thermal gradient in a direction approximately 30* off the c-axis. Conventional growth technique on either the a- or c-axis have not proven to yield satisfactory crystals from the standpoint of magnitude or yield.

Abstract: The hydrated and deuterated forms of lithium formate are found to be useful nonlinear materials for use over a wavelength range including the visible spectrum. While conversion efficiency is inferior to that of lithium niobate or barium sodium niobate, resistance to radiation damage is significantly greater. Operation at power levels in excess of 106 watts/cm2 has resulted in no perceptible damage. These materials are suitably incorporated in second harmonic generators as well as in other parametric devices.
