Latest Patents
Sigrid R Herd holds a patent for a groundbreaking invention titled "Zero to low magnetostriction, high coercivity, polycrystalline, Co-Pt." This patent describes an alloy of Co.sub.x Pt.sub.y with y between 10 and 30 at. %. The alloy is produced through sputtering, achieving high coercivity (H.sub.c >500 Oe) and a saturation magnetization (4.pi.M.sub.s >5000 gauss) while maintaining zero magnetostriction. The invention highlights that for 10 to 30 at. % Co, the sputtered alloy exhibits an H.sub.c of 500-1000 Oe and a 4.pi.M.sub.s of 4000-14000 gauss, with magnetostriction passing through zero between 20 and 30 at. % of Pt. The patent emphasizes that for thicknesses below 1000.ANG., the coercivity and magnetization are significantly enhanced, demonstrating a direct relationship with the Pt composition in the alloy.
