Few-dimensional Heisenberg ferromagnets at low temperature

A simple approximation for one- and two-dimensional Heisenberg ferromagnets is proposed. This is a modification of the spin-wave theory for a three-dimensi...

Magnetic Properties of Layered Transition Metal Compounds

In the last two decades low-dimensional (low-d) physics has matured into a major branch of science. Quite generally we may define a system with restricted dimensionality d as an object that is infinite only in one or two spatial directio...
