The magnetic stray field is an unavoidable consequence of ferromagnetic devices and
sensors leading to a natural asymmetry in magnetic properties. Such asymmetry is …

Micromagnetic modelling provides the ability to simulate large magnetic systems reliably
without the computational cost limitation imposed by atomistic modelling. Through …

The exchange coupling of two magnetic layers via a diffuse oxide interlayer is studied with
an atomistic spin model. We investigate the effect of magnetic concentration and oxide layer …

The macroscopic magnetic properties of nanocrystalline alloys are strongly dependent on
microstructural and micromagnetic inhomogeneities along with intergranular interactions. In …

As cloud computing and massive-data machine learning are applied pervasively, ultra-high
volume data storage serves as the foundation block. Every day, nearly 2.5 quintillion bytes …

This chapter discusses nanostructured magnetic thin films for data storage, including
overview of perpendicular recording media and FePt media for heat‐assisted magnetic …

Future magnetic recording media require firm control of the microstructure particularly with
uniform grain size at the nanometer scale. Using self-assembling block copolymers as an …

We report on continued measurements using an experimental model system to quantify
intergranular exchange coupling in CoCrPt-oxide perpendicular magnetic recording media …

Controlling the relaxation of magnetization in magnetic nanostructures is key to optimizing
magnetic storage device performance. This relaxation is governed by both intrinsic and …

In this paper, we present a set of systematic experimental investigations on possible noise
mechanisms for current perpendicular thin film media of small grain sizes. In particular, we …
