An authorization card, such as a credit card, has a security feature. The authorization card generally has two operational states, a disabled state and an enable state. In the disabled state, which is the default mode of operation, access to confidential information stored on the card is denied. The card remains in the disabled state until a PIN code is entered on a keypad provided on the card. Once the card is enabled, access to the confidential information is permitted for a predetermined period of time, after which the card reverts back to the default disabled state. The security feature is implemented on a magnetic card, an electronic smart card, and passive electronic card.

A magneto-optic memory and a magnetic material is described incorporating a polarized light beam directed towards a magnetic material and an analyzer for intercepting the polarized light beam after passing through the magnetic material or after being reflected by the magnetic material. The magnetic material includes a matrix of metal such as iron, cobalt, nickel, and alloys thereof and a plurality of separated phases distributed in the matrix such as EuS, EuO, EuOTb, PtMnSb, MnAs, MnBi, MnSb, CrO.sub.2, CrTe, GdN, Gd.sub.4 C, other compounds of a rare earth element and manganese compounds. Terbium or neodymium may be dissolved in the matrix of metal and in the plurality of separated phases.

A method for forming a giant magnetoresistance sensor and method for making is described incorporating an oriented granular layer wherein the layer has a copper matrix with magnetic particles of a nickel cobalt alloy wherein the magnetic particles have a magnetocrystalline anisotropy constant K.sub.1 in the range from 0 to 3.times.10.sup.4 ergs/cm.sup.3. Alternatively, a silver or gold matrix may be used with magnetic particles of a nickel-iron alloy. The granular layer preferably has a (100) texture to provide the magnetic particles with their easy axes in the plane of the layer. The magnetic particles have their largest dimension in the range from 40 to 400 angstroms. The invention overcomes the problem of requiring a large magnetic field to obtain the saturation .DELTA.R/R. By providing a granular film with magnetic particles of low anisotropy, the saturation field to obtain .DELTA.R/R may be as low as 10 to 20 Oe.

摘要:
Superconducting transition metal oxide films are provided which exhibit very high onsets of superconductivity and superconductivity at temperatures in excess of 40.degree. K. These films are produced by vapor deposition processes using pure metal sources for the metals in the superconducting compositions, where the metals include multi-valent nonmagnetic transition metals, rare earth elements and/or rare earth-like elements and alkaline earth elements. The substrate is exposed to oxygen during vapor deposition, and, after formation of the film, there is at least one annealing step in an oxygen ambient and slow cooling over several hours to room temperature. The substrates chosen are not critical as long as they are not adversely reactive with the superconducting oxide film. Transition metals include Cu, Ni, Ti and V, while the rare earth-like elements include Y, Sc and La. The alkaline earth elements include Ca, Ba and Sr.
