Abstract
The magnetic nature of a novel one-dimensional compound NaCr2O4 with zigzag CrO2 chains has been studied by muon spin rotation and relaxation (μ+SR) and neutron diffraction (ND). It is found that NaCr2O4 undergoes an antiferromagnetic transition at TN = 125K, below which the Cr moments in each zigzag chain align ferromagnetically along the c-axis but antiferromagnetically along the a-axis between adjacent zigzag chains. For the solid solution system Ca1-xNaxCr2O4, μ+SR measurements reveal the evolution of a complex magnetic order with increasing Ca content (1-x), which finally enters into an incommensurate AF ordered state below TN = 21 for CaCr2O4.
