Effect of high-energy heavy ion irradiation on magnetic properties of Ni–Mn alloys

Atomic diffusion in Ni–Mn mechanical alloys around Ni3Mn composition proved from magnetic measurements

“…Ni and Mn powders of the particle size of 100 mesh and the purity of 99.9% were mixed to the composition of 75 and 80 at.%Ni-Mn alloys, and milled for 75 h in a planetary ball mill in argon atmosphere using stainless steel balls and containers [3][4][5][6][7][8][9]. The product was annealed at the ordering temperature of 693 K for 50, 200, 500 and 1000 h to obtain partially and fully ordered states.…”

“…By using this technique it becomes possible to observe rapidly changing magnetic character of mechanical alloys during various heat treatments [3][4][5][6][7][8][9].…”
