Magnetic structure of the quasi-one-dimensional frustrated antiferromagnet LiCu2O2 with Spin S = 1/2

Abstract

The magnetic properties of LiCu2O2 single-crystal samples without twinning are investigated using electron spin resonance and nuclear magnetic resonance spectroscopy. The experimental results obtained are described in terms of the model of a planar spiral antiferromagnet for the orientation of the magnetic field H ‖ b or H ‖ c and the model of a collinear spin-modulated antiferromagnet for the orientation of the static magnetic field H ‖ a.
