Tom Wellsnsional Heisenberg triangular lattice antiferromagnet (2DH TAL-AF). One of the characteristic features of this frustrated system with continuous spin symmetry is that it undergoes a new type of phase transition at T.=0.66JS. driven by the pairing of the topological point defects known as Z. vorticie

In the present contribution we treat the . model, . and derive the parameter region in which long-range order certainly exists. We also show that long-range order along the non-principal axis (e.g. .-axis in the .-l

Successive Magnetic Ordering in a Triangular Lattice Antiferromagnet CsNiCl3 to be disordered (component disorder model), as has been supported by subsequent neutron diffraction measurements . However, a recent ESR experiment has shown that the model should be improved to include a dynamical character. In order to get more understanding, we have performed a detailed NMR

Evidence for Z2-Vortex Excitations in the Quasi-Two-Dimensional Triangular Lattice Antiferromagnets he first time, that the electron paramagnetic resonance (EPR) experiments can be used to extract valuable information about Z. vortex under some reasonable assumptions and provide experimental evidence for the existence of Z. vortex excitations in the highly 2D ordered temperature region of the quas

Soliton Dynamics in Impure Ising-like Antiferromagnetic Chainsd T.=9K. Short range order is well developed above T., and, in the intermediate phase (T.<T<T.), one-third of the magnetic chains still remain disordered. The presence of the coherent soliton in CsCoCl. for T>T. has been shown by the experiments of ESR and neutron scattering .
