Decrease permeability of ferromagnetic materials

  1. Oct 23, 2012 #1
    Hello.

    I know very few things about solid state physics, so my question is very basic.. I'm just searching for a clue..
    Have some of you ever heard about, or imagine a way, of decreasing the permeability of a ferromagnetic material? Not by raising temperature, but with electric field or electric current maybe?

    Thanks
    Best Regards
    Alexandre

    Check out this article for some insights:

    http://en.wikipedia.org/wiki/Saturation_(magnetic [Broken])

    note especially the second diagram.....

    and also note the PERMEABILITY "See Also' reference at the bottom of the page.

    Note that permeability is in general not a fixed constant and varies with the frequency of an applied electromagnetic field.
