Abstract
Magnetic properties of spin 1 2 J 1 – J 2 Heisenberg antiferromagnet on the body centered cubic lattice are investigated. By using two-time temperature Greenʹs functions, sublattice magnetization and critical temperature depending on the frustration ratio p = J 2 / J 1 are obtained in both stripe and Néel phases. The analysis of ground state sublattice magnetization and phase diagram indicates the critical end point at J 2 / J 1 = 0.714 , in agreement with previous studies.
