The magnetic properties and structures of Co 80 Pt 20–30 vol% oxide (ZrO 2, Cr 2 O 3, Y 2 O
3, Al 2 O 3, MnO, TiO 2, WO 2, SiO 2, Mn 3 O 4, WO 3, Co 3 O 4, MoO 3, and B 2 O 3) …

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 …

A method to evaluate the intergranular exchange coupling constant J EX in thin films with
perpendicular anisotropy, based on first order reversal curve (FORC) diagrams, is proposed …

Investigation of the effect of the melting point (Tm) of various single oxides on the columnar
growth and generation of the nucleation site for CoPt granular media deposited at room …

In this dissertation, using micromagnetic modeling based on the Landau-Lifshitz-Gilbert
equation, three types of advanced recording technologies have been studied and their …

The volume of a magnetic grain, together with its anisotropy, determines the probability of
thermally activated reversal. Thus for grain volume distributions where the median volume is …

The effects of temperature on intergranular exchange coupling for FePt: X: FePt (X= TaO x,
SiO x, Cr) sputtered thin film stacks were investigated. In-plane FePt layers separated by a …

Investigation of magnetic properties and microstructure for the Co 80 Pt 20-30 vol% B 2 O 3
granular medium deposited on Ru 50 Co 25 Cr 25-30 vol% oxide buffer layer (BL) with …

In this study we quantitatively determined the exchange coupling across B, C, SiO x, Cr and
TaO x segregants by measuring the exchange coupling between two FePt layers separated …
