The saga of magnetism started with the discovery of ferromagnetism of iron in the early stage of human history. Magnetism has contributed importantly to human life, as we can …

The magnetic susceptibility of single-crystal CuGeO 3, a linear Cu 2+(spin-1/2) chain compound, was measured. The susceptibilities in all the directions rapidly drop to small …
We use non-abelian bosonization to predict critical exponents for quantum chains of arbitrary spin and arbitrary symmetry SU (n). Passing to the large representation limit gives …
G Müller, H Thomas, H Beck, JC Bonner - Physical Review B, 1981 - APS
Spin-dynamical calculations on one-dimensional systems have relied heavily on classical (s=∞) theories, despite abundant evidence that quantum effects can be extremely important …

Inorganic compounds with the AB2X4 spinel structure have been studied for many years, because of their unusual physical properties. The spinel crystallographic structure, first …
We develop a new theory of the spin-Peierls transition in spin-½ Heisenberg chains, treating the phonons in a mean-field random-phase approximation (RPA) as in previous work, but …

Mott insulators are identified here with ordinary magnetic insulators. The insulating gap, local moment, and effective spin hamiltonian aspects are qualitatively explained by means …
Magnetic susceptibility and inelastic neutron scattering experiments have been performed in the nearly ideal one-dimensional Heisenberg antiferromagnet with spin one, Ni (C 2 H 8 N …
