I mean if someone did ferromagnetic amorphous with two separate magnetic phases at different temperatures Curie. In addition, if these materials have a high Ms small Hc.
Hi Marcin
I am not quite sure how one would make bulk ferromagnetic amorphous alloys with two amorphous phases. The only way you can separate two different phases in amorphous alloys when the amorphous structure transforms to crystalline phases.
Hi Khaled. I am glad that you become interested in my question. I have done such materials and even I have published on this topic. This subject really interests me. I wanted to see if anyone else is doing these things.
I tend to agree with Mr. Habib. I have worked for a long time with amorphous bulk (ribbons) and I wonder how to define a phase bec there is No structure in a truly amorphous alloy. It is a just a solid sloution. Hwever if your alloy is not purely amorphous then you migh two or three different pahase inwhich case it is no longer an amorphous alloy. I would be interested in knowing from you about your work;
Dear all,
imagine a traditional phase diagram. At the highest temperature there is the 'liquidus' line........
If you think about it, shouldn't there be much more than just 'liquidus' above it? It is apparent that there are a multitude of small -scale structures in the molten state. I believe one should think of the space above liquidus as a portion (possibly) at least as complicated as in the solid state.
The Problem (with capital letters) is that these are so much more difficult to see and identify!
There is much room at the top!

I think that what's Marcin wanted to say is the existence of two (or more) chemically non equivalent amorphous 'phases' (or matrices), not phases in the crystalline structure sense.
That's exactly what I got two effects seen with measurements on magnetic weight . It is clear then, that there are two magnetic phases. I wonder if they could be two amorphous phases.
May be 2 different nanocrystalline phases was allocated in your amorphous substance?
And what results are obtained from x-ray analysis?
