Abstract: A print ribbon for an impact printer uses a heavy-duty 70/70 denier fabric having approximately 230 threads per square inch. The fabric can be textured. The print ribbon uses an ink having a viscosity of approximately 2000 cps to 3400 cps, a liquid pigment, and a color strength of approximately 1.5 to 2.0, with the pigment content being 15% or less (e.g., 2.5%) and the ribbon having an ink concentration of approximately 19%.

Abstract: This invention relates to magnetic tunnel junctions and methods for making the magnetic tunnel junctions. The magnetic tunnel junctions include a tunnel barrier oxide layer sandwiched between two ferromagnetic layers both of which are epitaxial or textured with respect to the underlying substrate upon which the magnetic tunnel junctions are grown. The magnetic tunnel junctions provide improved magnetic properties, sharper interfaces and few defects.

Abstract: Zirconium-rich bulk metallic glass alloys include quinary alloys containing zirconium, aluminum, titanium, copper and nickel. The bulk metallic glass alloys may be provided as completely amorphous pieces having cross-sectional diameters of at least about 5 mm or even greater.

Abstract: Magnetic tunnel junctions and method for making the magnetic tunnel junctions are provided. The magnetic tunnel junctions are characterized by a tunnel barrier oxide layer sandwiched between two ferromagnetic layers. The methods used to fabricate the magnetic tunnel junctions are capable of completely and selectively oxidizing a tunnel junction precursor material using an oxidizing gas containing a mixture of gases to provide a tunnel junction oxide without oxidizing the adjacent ferromagnetic materials. In some embodiments the gas mixture is a mixture of CO and CO2 or a mixture of H2 and H2O.
