摘要：

The invention relates to a method for producing organic substrate particles bound to switchable ferromagnetic nanoparticles having a mean particle diameter in the range of 10 to 1000 nm, wherein nanoparticles that are at first not ferromagnetic but become ferromagnetic upon lowering of the temperature are used, said at first non-ferromagnetic nanoparticles are bonded to the organic substrate particles in a dispersed form and subsequently the nanoparticles bonded to the substrate particles are made ferromagnetic by the lowering of temperature.
