Abstract: A magneto-optical device (MOD) with optically induced magnetization for use in magnetic field sensors as a magnetic element pinning a magnetization in a preferred direction of a ferromagnetic layer as well as a magnetic memory cell for magneto-optical recording. The MOD comprises the Mg—Mg—Co ferrite film deposited on a magnesium oxide (MgO) substrate. The ferrite film is illuminated at room temperature with a circularly polarized light (CPL) in a static magnetic H-field (about of 3 kOe) normal to the illuminated ferrite film surface. At certain (“writing”) combinations of H, sigma (CPL helicity), the long-lived optically induced magnetization with a unidirectional anisotropy, stable to a conventional demagnetization occurs. For readout of information, conventional magnetoresistive sensors and MFM can be used. To erase information, the ferrite film should be illuminated with two field-light combinations, other than “writing”, or annealed at temperature higher than 530 degrees C.

Abstract: The present invention relates generally to the storage of information on magnetic and/or optical storage media by using one or more novel approaches alone or in combination. These novel approaches are capable of using at least one code which may comprise more than two values (i.e., more than a “0” and a “1”). A first series of approaches for the storage of information applies generally to optical storage/retrieval systems (e.g., CD's, DVD's, etc.); while a second series of approaches applies generally to electric and/or magnetic storage/retrieval systems (e.g., magnetic, magneto-optic, etc.). Each series of approaches is capable of storing information in one or more codes, wherein such approaches permit, if desired, the use of at least one higher order code which is different from the traditional binary code of “0's” and “1's” currently utilized for the storage of digital information. Said at least one higher order code may comprise three or more optical and/or magnetic values or bits that are used to represent, for example, ASCII or Unicode characters that are currently represented predominantly by the traditional binary code. This higher order code may also be an analog or analog-like code.

Abstract: A resonator system comprises an optical resonator that supports one or more pairs of nearly degenerate defect states. One or more magnetic domains comprising at least one gyrotropic material in the optical resonator cause magneto-optical coupling between the two states so that the system lacks time-reversal symmetry. In one embodiment, a single magnetic domain is used that dominates induced magneto-optical coupling between the defect states. The above resonator system may be used together with other components such as waveguides to form circulators, add drop filters, switches and memories.

Abstract: A magnetic layer for storing information in the form of a fixed, two-dimensional array of magnetic domains. The magnetic layer can be magnetized in either of two opposite directions normal to the plane of the layer. The walls of the domains are fixed by local gradients in the value and direction of the magnetic anistropy and in the value and direction of the magnetic exchange energy of the magnetic layer. The local gradients may be caused by a relatively high defect density at the domain wall locations, by implanting ions into the magnetic layer at the locations of the domain walls thereby causing a local expansion of the crystal lattice of the layer, and/or by etching a multiplicity of nonconnected tapering channels in and substantially perpendicular to the plane of the magnetic layer at these locations. Where tapering channels are used, the magnetic layer is provided on a substrate such that the crystal lattice constant of the magnetic layer is different from the crystal lattice constant of the substrate. In another embodiment, the local gradients can be the result of the epitaxial growth of a magnetic layer on a substrate which has a plurality of nonconnected etched channels at the domain wall locations.
