Paper Title:
Spontaneous Magnetization and Antiferromagnetic Correlations in Low-Dimensional Quantum (S=1/2) Single Crystal LiCu2O2+Δ
  Abstract

The low temperature investigations of the magnetic properties of non-twinning LiCu2O2+δ crystals showed that a new spontaneous magnetization phase arises in the compound at temperatures less than T~150 K along with the basic long-range helimagnet phase at T<24 K. The increase of an extra oxygen Оδ concentration intensifies ferromagnetic response of this phase. We suggested a cluster model for the new phase as an antiferromagnet structure with a short-range order with the weak and hidden ferromagnetism on the basis of both the theoretical group analysis of the magnetic and crystal lattice symmetry and the analysis of the temperature, field, hysteresis and anisotropy properties of spontaneous magnetization.
