Introduction

Isabel Goncalves Trindade is a prominent inventor based in Pittsburgh, PA (US). She has made significant contributions to the field of magnetic materials, holding a total of six patents. Her work focuses on developing advanced multilayer permanent magnet films and innovative magnetic read head technologies.

Latest Patents

One of her latest patents involves multilayer permanent magnet films that comprise at least two permanent magnet layers separated by an interlayer. In this embodiment, the multilayer permanent magnet film includes an interlayer deposited on a first permanent magnet layer, a seed layer deposited on the interlayer, and a second permanent magnet layer deposited on the seed layer. The permanent magnet layers may comprise a material such as CoPt, while the seed layer may comprise a material such as TiW. The interlayer may comprise a material such as Ta. These multilayer permanent magnet films possess favorable properties such as high magnetic coercivity and high remnant magnetization at thicknesses that yield high magnetic fields. The films may be utilized in applications such as current perpendicular to the plane (CPP) magnetic sensors, where the multilayer permanent magnet film is used to magnetically bias the sensor.

Another notable patent focuses on a magnetic read head wherein the shields are used as electrical leads and have a minimized anisotropic magneto-resistance effect. This ferromagnetic shield material allows for the use of a combined shield/electrical lead for magneto-resistive read elements. Consequently, the shields/electrical leads can be placed closer together, maximizing the recording density that can be read by a magnetic recording head using a read element equipped with such shields/leads.
