BINARY MIXTURES OF FERRO- AND ANTIFERROMAGNETIC BONDS IN QUANTUM SPIN-1 MODELS : CRITICAL BEHAVIOR
Carla Buzano
A quantum spin-1 model, describing a mixture of ferro- and antiferromagnetic bonds, is analyzed employing the effective Hamiltonian method extended to random systems. Uniform, staggered and spin-glass susceptibilities are introduced and Curie, Néel and spin-glass transition temperatures determined. The role anisotropy is examined.
