Query: Antiferromagnetic phase transition in $Cr_{2}As$ via anisotropy of
  exchange interactions   The electronic structure of anti-ferromagnetic $Cr_{2}As$ is investigated.
Anisotropy of exchange interactions between chrome sub-lattices is determined
($J^{X}(Cr_{I}-Cr_{II}) =4.77 meV,J^{Y}(Cr_{I}-Cr_{II}) =-6.36 meV$). The
behavior of exchange integrals from magnetic structure is analyzed.
