“…As the described features of χ(T) curve can be attributed to AFM ordering we can assume that a new type of antiferromagnetic ordering-field induced AFM has been found experimentally [2]. According to the theoretical model of Nagaev [3], the long-range antiferromagnetic order in two-dimensional spin-1/2 Heisenberg frustrated systems can be induced by external magnetic field because it decreases the angles between magnetic moments in the magnetic sublattice and suppresses quantum spin fluctuations hindering AFM ordering in such systems at Τ = 0. The additional favourable factors might be the magnetic anisotropy, interplane exchange interaction, and interaction of 1/2 spins with large spins of rare-earth metals [4].…”
