Single crystal production is determined much more by the crystallization technology and by the purity of the materials used rather than by the melting technology. In order to grow single crystals you need slow cooling, pure materials and avoidance of multiple seeding. (Zone melting, Czochralski method etc.). Please give more details of your project, so specialist around (I am not one of them) might help you specifically.
Dear Gyorgy,
Thanks to share your ideas. I am looking to make a composition of X2YZ (Where X and Y are transition metals and Z is a non magnetic element).
Hello Lakhan,
Your answer, "I am looking to make a composition of X2YZ (Where X and Y are transition metals and Z is a non magnetic element)" to Gyorgy's perfectly justified query is quite amusing. You are asking for a "quick response" on a materials processing issue from peers in an international forum without specifying the facts required to answer your question! By doing this, you are showing even your institution in poor light.
If you think that disclosing details of your materials will compromise the novelty of your work, why don't you try to find the answers from the scientific literature yourself!
Dear Kanad,
Actually i didn't plan exact composition thats why i replied like this..If you know something about this please share here, if need some more information please tell.
Dear Lakhan,
What you are saying means that you are ready to choose from about 30+ transition metals and other non-magnetic metals! Doesn't your or your group's research track lead you to a more informed and requirement-specific choice? My own background is in semiconductors and I have worked with transition metal impurities in single-crystal silicon. I have only a little familiarity with magnetic metallic multilayers etc which I do not think will be of any help to you. Your post really surprised me and that's why I could not refrain from asking you.
Best wishes
Dear Kanad,
What about making Co2MnSi?..What precautions should i care while try with arc melt furnace.
Dear Lakhan,
As I said, this is outside my area of expertise. However, a quick look over the internet indicates that Co2MnSi has only been grown in thin film form by techniques like PLD and sputtering on different substrates. First, you need to make sure how difficult it is thermodynamically to grow crystalline Co2MnSi in bulk form from its phase diagram. Then you need to maintain the composition and condition of the melt by controlling your furnace over time and temperature during the growth process. Usually, a single crystal seed is required to facilitate crystal growth. There should be a mechanical arrangement to pull the seed with the growing crystal from the melt. It is of primary importance to maintain purity level (99.9999% by semiconductor standards) of the starting material and melt which means your furnace should also be super clean.
Dear Kanad sir,
Thanks for sharing your ideas. But Co2MnSi is also reported in bulk form
