ACCOMMODATION STUDY OF A NANOGRAIN IRON-POWDER

Accommodation (reptation) is a magnetizing process which occurs when t he field is cycled between two extrema. The resulting minor loops do n ot close upon themselves, but rather approach a closed limit cycle wit h each application of the applied field extrema. This paper shows that there is significant accommodation in an evaporated nanograin iron po wder. The shape of the accommodating loops depends on the applied fiel d extrema.
