In: Journal of Applied Physics Nr. 10, Jg. 75(1994), S. 6057-6059, doi: 10.1063/1.355509.http://hdl.handle.net/2003/2543210.17877/DE290R-3444The one-dimensional spin-s XYZ model in a magnetic field of particular strength has a ferro- or antiferromagnetically ordered product ground state. The recursion method is employed to determine T=0 dynamic structure factors for systems with s=1/2, 1, 3/2. The line shapes and peak positions differ significantly from the corresponding spin-wave results, but their development for increasing values of s suggests a smooth extrapolation to the spin-wave picture.enAmerican Institute of Physics51010.1063/1.355509article (journal)
