Abstract
Selfconsistent ab initio calculations based on density functional theory DFT approach and using fullpotential linear augmented plane wave FLAPW method are performed to investigate both electronic and magnetic properties of the MnAu nanowire Polarized spin and spinorbit coupling are included in calculations within the framework of the antiferromagnetic state between two adjacent Mn layers in MnAu nanowire Magnetic moments considered to lie along the caxes are computed Obtained data from ab initio calculations are used as input for the high temperature series expansions HTSEs calculations to compute other magnetic parameters The zerofield high temperature static susceptibility series of the magnetic moment m and nearest neighbour Ising model on a MnAu nanowire is thoroughly analyzed by means of a power series coherent anomaly method CAM for different layers The exchanges interactions between the magnetic atoms the critical exponent associated with the magnetic susceptibility are obtained for MnAu nanowire with different layers
