Abstract :
Accommodation (reptation) is a magnetizing process which occurs when the field is cycled between two extrema. The resulting minor loops do not close upon themselves, but rather approach a closed limit cycle with each application of the applied field extrema. This paper shows that there is significant accommodation in an evaporated nanograin iron powder. The shape of the accommodating loops depends on the applied field extrema
