摘要：

Magnetic properties of alpha-CuV2O6 with linear chains of edge-sharing CuO6 octahedra were studied by magnetic susceptibility and electron spin resonance measurements. The broad maximum of magnetic susceptibility at T-M = 44 K, corresponding to the intrachain exchange interaction J(1) = 34 K, indicates one-dimensional short-range magnetic ordering within the chains. Three-dimensional long-range antiferromagnetic ordering takes place at T-N = 24 K suggesting a rather big value for the interchain exchange interaction J(2) similar to 13 K. The 76 GHz energy gap, found in the antiferromagnetic resonance spectrum, agrees with the spin-flop magnetic field value of about 2.7 T. (C) 2000 Published by Elsevier Science B.V.
