Decrease permeability of ferromagnetic materials

Click For Summary
SUMMARY

Decreasing the permeability of ferromagnetic materials can be achieved through methods other than temperature elevation, such as applying an electric field or electric current. The discussion highlights that permeability is not a fixed constant; it varies with the frequency of the applied electromagnetic field. Alexandre references an article on saturation in magnetic materials, emphasizing the importance of understanding permeability in this context. This indicates that exploring alternative methods to manipulate permeability is a viable area of research in solid-state physics.

PREREQUISITES
  • Understanding of solid-state physics principles

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 )

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.
