Abstract: K1.00194 : Composition Dependence of the Anomalous Hall Effect in L10 FePt Thin Films
Author:
FePt multi-layered thin film systems were investigated as to its
composition
effect on the anomalous hall effect. Thin bilayers of FePt were
sputter-deposited in series of variable thicknesses on to a
thermally
oxidized substrate of SiO2. The total thickness of samples was
controlled to
be 12 nm. XRD and SEM were used to confirm structure and
composition of thin
films for systematic characterization. Resistivity and Magnetization
measurements were studied at room temperature and low temperature
using
SQUID magnetometer. The minimal resistivity exists near 54{\%} of Fe
concentration. The anomalous hall effect dominates as Fe
concentration
increases. Hall angles drop rapidly at the both high and low Fe
concentration while it exhibits a plateau-like dip near 54{\%} of Fe
concentration.
