Phase diagram of spin-$\frac 12$ quantum Heisenberg $J_1-J_2$ antiferromagnet on the body-centered-cubic lattice in random phase approximation

Magnetic properties of spin $\frac{1}{2}$ $J_{1} - J_{2}$ Heisenberg antiferromagnet on body centered cubic lattice are investigated. By using two-time temperature Green’s functions, sublattice magnetization and critical temperature depending on the frustration ratio $p = J_{2} / J_{1}$ are obtained in both stripe and N'eel phase. 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.
