  journal={Physical Review B},
The compound MnAu$_2$ is one of the oldest known spin-spiral materials, yet the nature of the spiral state is still not clear. The spiral cannot be explained via relativistic effects due to the short pitch of the spiral and the weakness of the spin-orbit interaction in Mn, and another common mechanism, nesting, is ruled out as direct calculations show no features at the relevant wave vector. We propose that the spiral state is induced by a competition between the short-range antiferromagnetic… Expand

Microscopic origin of ferro-antiferromagnetic transition upon non-magnetic substitution in Ru2(Mn1−xVx)Ge full Heusler alloys
Abstract On the basis of first-principle simulations of interatomic magnetic exchange interactions, we show that the transition from antiferromagnetic order in Ru 2 MnGe to ferromagnetic order inExpand
Magneto-electric coupling in antiferromagnet/ferroelectric Mn2Au/BaTiO3 interface
Within the crucial issue of the electric field control of magnetism, the use of antiferromagnets (AFMs) coupled to ferroelectrics is much less explored than the ferromagnets counterpart, although theExpand
New antiferromagnetic order with pressure-induced superconductivity in EuFe2As2
The interplay between magnetism and superconductivity is one of the important subjects to investigate the pairing mechanism in novel superconductors. We have found a new coexistence between anExpand
Pressure tuning of collapse of helimagnetic structure in Au 2 Mn
We identify the phase boundary between spiral spin and ferromagnetic phases in Au$_2$Mn at a critical pressure of 16.4 kbar, as determined by neutron diffraction, magnetization and magnetoresistanceExpand
Magnetic properties of dysprosium – Experiment and modeling
Abstract Here we present the continuation of the approach developed in our previous work [1] taking another lanthanide metal – Dy – as an example. The rich set of the experimental data which includesExpand
Growth and characterization of MnAu 2 films
Abstract MnAu 2 films ranging from 60 to 200 nm thickness are deposited by co-sputtering from elemental targets. X-ray diffraction confirmed these films to be nearly single phase with tetragonalExpand
