All-metal current-perpendicular-to-plane (CPP) giant magnetoresistance (GMR) read sensors with a shield-to-shield spacing (S2S) of 16–21 nm and a narrow track width of down to 25 nm were fabricated using ferromagnetic CoFeMnSi Heusler-alloy-based s

Magnetic Heusler alloys that benefit from their half-metal characteristics have recently seen significant progresses in material researches and process development. As a result, current perpendicular to plane (CPP) giant magnetoresistance (GMR) has b

Chemically synthesized FePt nanoparticles have potential for application as magnetic media for data storage. In order to be used as data storage media, however, they must be deposited on substrates in such a way that their magnetic axes are aligned w

In this paper we discuss various microstructural features that control the recording properties of thin films used in perpendicular recording. These microstructure features include crystallographic texture, grain size, grain size distribution, grain

FePt/iron oxide core/shell nanoparticles are synthesized by a two step polyol process with 1,2-hexadecanediol as the reducing reagent. Monodispersed 2.6-nm FePt nanoparticles are first obtained by reduction of iron(III) acetylacetonate and platinum(I

Spin-valve structures might be exposed to higher temperatures in future disk drive applications and might thus degrade faster than it does today if proper materials and methods are not used. In order to determine whether this degradation is due to in

Signal degradation in spin-valve structures is today a concern for long-term stability of data storage devices. One of the possible degradation mechanisms of spin-valve structures in disk drive applications could be thermally activated diffusion betw

The influence of oxide additives on the magnetic and structural properties of FePt L1 0 thin films has been studied. FePt films with HfO 2 additive grown on a 5 nm MgO buffer showed a primarily random texture for both as-deposited and annealed sample

The influence of Cu, Ag, and Au additives on the L10 ordering, texture, and grain size of FePt thin films has been examined. Lattice parameter data indicated that Au and Ag additives tended to segregate from FePt, but Cu alloyed with FePt. FePt films
