摘要

Experimental results on magnetic resonance (ESR) and magnetic susceptibility are given for single crystalline (VO)_2P_2O_7. The crystal growth procedure is briefly discussed. The susceptibility is interpreted numerically using a model with alternating spin chains. We determine J = 51 K and δ = 0.2. Furthermore we find a spin gap of ≈6 meV from our ESR measurements. Using elastic constants no indication of a phase transition forcing the dimerization is seen below 300 K.
