摘要： A method and apparatus for storing data and for reducing the magnetic moment of a ferromagnetic material is provided incorporating a magnetic film, a blanket or patterned film of germanium adjacent the magnetic film, and means for heating the interface of the two films to at least 200.degree. C. to permit diffusion of the germanium into the magnetic film and thereby reduce the magnetic moment. The invention overcomes the problem of forming recording tracks on storage media and patterning magnetic films for inductive and magneto resistive heads for retrieving data from moving storage media.

摘要： A magneto-optic memory and storage medium with the ability to directly write or overwrite ones and zeros at recording speed is described incorporating a radiant energy source, a control circuit for adjusting the power of the radiant energy beam and magneto-optic medium having a three layer sandwich comprising a magnetic bias layer, storage layer, and a switching layer therebetween functioning to switch from an antiferromagnetic state at low temperatures to a ferromagnetic state at temperatures above T.sub.AF. The invention overcomes the problem of direct overwrite of ones and zeros on magneto-optic media.

摘要： A thermochemical magnetic generator system utilizes a gas, preferably hydrogen, and a material, such as LaCo.sub.5, which varies in magnetization upon addition of the gas to the material to generate electricity from a magnetic circuit which includes the magnetizable material in the circuit. When the gas partial pressure is reduced or heat is applied to the material which has combined with the gas, then the gas is driven off in a thermochemical reaction which reverses the magnetization of the system. In particular, the addition of hydrogen gas to LaCo.sub.5 reduces the magnetization and its removal from the material increases the magnetization. Rapid reversal of the pressure cycle or heating and cooling cycles with a plurality of chambers through which the gas is admitted and exhausted reversibly can be used as a source of electricity.

摘要： There is disclosed herein a relatively low-cost, high density postable storage medium which comprises adjacent thin layers of two or more materials which react upon heating to form a reaction product with optical, magnetic or electrical properties different from the corresponding properties of the reactant materials. Thus, utilizing reactant layers such as aluminum and selenium, the heating results in a reaction product of Al.sub.2 Se.sub.3. The heating agent is notably a laser beam.
