    Graduate Exchange coupling constant in micromagnetic simulation

    Hi, all. I'm wondering if anyone's done some simulation of magnetic material with LLG equation. The question is where can I find the value of exchange constant for a material. In LLG equation, the exchange constant is in the unit of "J/m", and the typical value is 10^-11 J/m, for some...
