✦ Synopsis

Spin dynamics of a 2D Heisenberg ferromagnet of K>CuF, with easy plane anisotropy have been investigated with high resolution inelastic neutron scattering above T,. In addition to spin waves, a central peak has been measured and interpreted in terms of the dynamics of free spin vortices
