Ab-Initio Study on the Magnetic Structures in the Ordered Mn $_{3}$Pt Alloy

We study the electronic states of the magnetically ordered Mn
₃
Pt alloy within the density functional theory. Mn
₃
Pt has been believed that one third of Mn atoms have no magnetic moment in an antiferromagnetic phase (so-called the F-phase) realized in the temperature range of 400 K
