摘要: The technique of “field sweep-rate dependence coercivity” together with the delta-M curves, transmission electron microscopy, and media noise measurement have been employed to reveal correlation among magnetic switching volume, physical grain size, intergrain interaction, properties. volume for both CoCrTa CoCrPtTa films was found be ∼15 nm in diameter, weakly dependent on size coercivity systems studied. In larger than strong interaction high is observed. close smaller interactions lower found. It argued that a change results nature interactions.
