dc.description.abstractc/a ratio effects on the magnetic properties of the Mn2NiB Heusler alloy are investigated by using effective field theory developed by Kaneyoshi. It is found that the Curie temperature and coercive fields of the Mn2NiB are obtained as Tc-IT > Tc(C) > Tc-NT = 0.92 and Hc(IT) > Hc(C) > Hc(NT) = 0.00 for c/a < 1 (inverse tetragonal), c/a = 1 (cubic), and c/a > 1 (normal tetragonal), respectively. These magnetic differences show that the c/a ratio causes a perpendicular magnetic anisotropy (PMA). Therefore, we suggest that PMA strongly depends on the c/a ratio, atomic distance, and exchange interactions between two atoms (Mn-Ni and Mn-B) on the ca surfaces of the Mn2NiB.
