Recently, however, organic and molecular materials have begun to show increasing …

Magnetic TTF-based charge-transfer complexes

T Enoki, A Miyazaki - Chemical reviews, 2004 - ACS Publications
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 …

Observation of the spin-Peierls transition in linear (spin-1/2) chains in an inorganic compound

M Hase, I Terasaki, K Uchinokura - Physical Review Letters, 1993 - APS
The magnetic susceptibility of single-crystal CuGeO 3, a linear Cu 2+(spin-1/2) chain

Exact critical exponents for quantum spin chains, non-linear σ-models at θ= π and the quantum hall effect

I Affleck - Nuclear Physics B, 1986 - Elsevier
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 …

Quantum spin dynamics of the antiferromagnetic linear chain in zero and nonzero magnetic field

G Müller, H Thomas, H Beck, JC Bonner - Physical Review B, 1981 - APS

Formation of isomorphic Ir3+ and Ir4+ octamers and spin dimerization in the spinel CuIr2S4

PG Radaelli, Y Horibe, MJ Gutmann, H Ishibashi… - Nature, 2002 - nature.com
Inorganic compounds with the AB2X4 spinel structure have been studied for many years,
because of their unusual physical properties. The spinel crystallographic structure, first …

A new theory of the spin-Peierls transition with special relevance to the experiments on TTFCuBDT

MC Cross, DS Fisher - Physical Review B, 1979 - APS
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 …

Electronic structure of Mott insulators

BH Brandow - Advances in Physics, 1977 - Taylor & Francis
Mott insulators are identified here with ordinary magnetic insulators. The insulating gap,
local moment, and effective spin hamiltonian aspects are qualitatively explained by means …
