Research output: Contribution to journalArticlepeer-review


The dynamic magnetisation reversal behaviour of polycrystalline Ni80Fe20 films (thickness 60 and 200 Å) was studied in the temperature range 90-300 K. The loop area A is found to follow the scaling relation A∝H0αΩ βT with α≈0.9, β≈0.8, and γ = 0.38 for both thicknesses. The exponents α and β are found to be independent of the temperature, indicating that the dynamic reversal mechanism is unchanged in this temperature range.
