"Layered antiferromagnetism with high Neel temperature in the intermetallic compound Mn2Au";
Applied Physics Letters, 93 (2008), 1625031 - 1625033.



English abstract:
On the basis of earlier experimental studies the intermetallic compound Mn2Au has been
characterized as a nonmagnetically ordered material. Here we report the results of first-principles
calculations based on local spin-density approximation that describes Mn2Au to have a narrow band
ground state with rigid local moments on the Mn sites. Calculations of the interatomic exchange
constants based on the magnetic force theorem and a Monte Carlo modeling of the resulting
Heisenberg-like Hamiltonian predict a high Neel temperature of 1600 K. This temperature is
considerably higher than for the other known high-temperature antiferromagnetic L10-type Mn
based binary alloys used in magnetic storage applications. 2008 American Institute of Physics.\
