    Doublings of Soliton Modes and Soliton Magnetic Resonance (SMR)

    In the field of non-linear excitations, antiferromagnetic (AF) Ising-like chains are expected to reveal new and basic features concerning the physics in onedimension. In particular, in the case of classical sp...

    Critical fluctuations in the 2D XY antiferromagnet BaNi2(PO4)2 : NMR measurements

    Non-linear excitations are known to play a crucial role in low-dimensional magnetism. For the two-dimensional (2D) XY model these non-linear excitations are described in terms of vortices which govern the so-c...
