Magnetization above Curie Temperature

[jglezag]

Hi all,
I'm preparing a talk about Curie Temperature, and looking for some Ms(T) graphs in the web I've found some of them in which the magnetization is not zero when T > Tc, (the dramatic change is obversable, so it is the Tc). But for T > Tc I expect complete disorder and no domains, then Ms=0. Is there any reason for having Ms (T>Tc) >0?

It might help if you bothered to tell us what "Ms" is. But in case you are asking this: The magnetization of a paramagnetic substance is usually not zero if you apply an external magnetic field. Moreover, even in the absence of an external magnetic field and the existence of a critical temperature magnetization, domains are expected above but close to the critical temperature.
What I am saying here is of course a complete shot in the dark since I find your post a bit non-saying. But perhaps it still helps you.

Thanks Timo. And sorry for making you guess. I've been seeing so many graphs lately that I didn't realize I wasn't explaining what symbols meant. Ms, as you correctly guessed, is magnetization of saturation, anf Tc the Curie Temperature. (I was thinking more on ferromagnets).
