Magnetic properties of isolated DyN clusters are studied in a molecular beam
performing Stern-Gerlach experiments. The magnetizations 
of DyN are measured in dependence of
the magnetic field strength B=0-1.6 T and at nozzle temperatures Tn=18 K
and Tn=300 K. At room temperature the magnetization augments linear with the field
following a simple paramagnetic model. At Tn=18 K the magnetization curves saturate at
field strengths 
T. To explain the magnetization process at low temperatures two
models are
discussed: A model for adiabatic magnetization based on cluster
rotation effects and a modified van-Vleck model.
