摘要： A high performance TMR sensor is fabricated by employing a free layer with a trilayer configurations represented by FeCo/CoFeB/CoB, FeCo/CoB/CoFeB, FeCo/CoFe/CoB, or FeCo/FeB/CoB may also be employed. Alternatively, CoNiFeB or CoNiFeBM formed by co-sputtering CoB with CoNiFe or CoNiFeM, respectively, where M is V, Ti, Zr, Nb, Hf, Ta, or Mo may be included in a composite free layer or as a single free layer in the case of CoNiFeBM. A 15 to 30% in improvement in TMR ratio over a conventional CoFe/NiFe free layer is achieved while maintaining low Hc and RA

摘要： A method of forming a high performance magnetic tunnel junction (MTJ) is disclosed wherein the tunnel barrier includes at least three metal oxide layers. The tunnel barrier stack is partially built by depositing a first metal layer, performing a natural oxidation (NOX) process, depositing a second metal layer, and performing a second NOX process to give a MOX1/MOX2 configuration. An uppermost metal layer on the MOX2 layer is not oxidized until after the MTJ stack is completely formed and an annealing process is performed to drive unreacted oxygen in the MOX1 and MOX2 layers into the uppermost metal layer. In an alternative embodiment, a plurality of metal oxide layers is formed on the MOX1 layer before the uppermost metal layer is deposited. The resulting MTJ stack has an ultralow RA around 1 ohm-μm2 and maintains a high magnetoresistive ratio characteristic of a single metal oxide tunnel barrier layer.

摘要： The present disclosure encompasses compositions comprising a surfactant, and an acid such as, but not limited to, levulinic acid, that together have a synergistic effect in reducing the viability of a virus population compared to the efficacy of the individual compounds. This synergy allows the formulation of compositions where the active agents (including an acid and a surfactant) are present at concentrations effective to inactivate viruses on surfaces, including human skin. The viricidal compositions disclosed herein are efficacious without damaging the surface to which they may be applied, or even altering the organoleptic properties of a treated food substance. The viricidal compositions and wipes containing such compositions are suitable for sanitizing any surface suspected of having a viral load thereon, or where it is desirable to ensure that a viral load is as low as possible.

摘要： A magnetic sensor, formed from a pair of magnetically free layers located on opposing sides of a non-magnetic layer, and method for its manufacture, are described. Biasing these free layers to be roughly orthogonal to one another causes them to be magnetostatically coupled in a weak antiferromagnetic mode. This enables the low frequency noise spectra of the two free layers to cancel one another. Careful control of the SH/TW ratio is an important feature of the device.

摘要： The presently disclosed technology teaches an improved voltage pattern for conductive tips utilized as moveable top electrodes for writing data bits into ferroelectric media. A conductive tip is dragged in contact or near contact with a ferroelectric surface forming a moveable top electrode on a ferroelectric media disk. A metallic film is deposited onto a bottom-side of the ferroelectric media forming a conductive bottom electrode. Applying electrical voltage pulses between the conductive tip and the bottom electrode induces polarization switching of the ferroelectric media under the head. The improved voltage pattern incorporates positive and negative overshoot voltages to induce a polarization switch in the ferroelectric media and positive and negative drag voltages to expand a polarized region on the ferroelectric media. Potential benefits of the improved voltage pattern include reduced cross-track blooming and reduced along-track blooming resulting in a more uniform track width and bit series length.

摘要： A method of writing to ferroelectric storage medium includes the steps of applying a first write voltage to a ferroelectric layer for writing a first bit in a first polarization direction and applying a second write voltage to the ferroelectric layer for writing a second bit in a second polarization direction opposing the first polarization direction. The first write voltage having a first magnitude, and the second write voltage having a second magnitude being greater than the first magnitude. The ferroelectric layer having a ferroelectric imprint polarization direction, and the first polarization direction being substantially the same as the ferroelectric imprint polarization direction. The ferroelectric medium contains first bits with a first surface area that is substantially equal to second bits surface area. A probe storage apparatus can use this method and ferroelectric medium.
