The particles are dispersible in chloroform resulting in stable suspensions. Magnetic response against an external magnetic field proved the superparamagnetic nature of the particles with a low coercivity (B-c) value of 297 mu T. The combination of the advantageous superparamagnetism of the mgNP with the exceptional stability of OPDL makes these novel hybrid mgNP promising candidates as multifunctional building blocks for magnetic nanocomposites with tunable physical properties.}, language = {en} } @phdthesis{Frank1999, author = {Frank, Ute}, title = {Rekonstruktion von S{\"a}kularvariationen des Erdmagnetfeldes der letzten 100.000 Jahre - Untersuchungen an Sedimenten aus dem Lago di Mezzano und dem Lago Grande di Monticchio, Italien}, address = {Potsdam}, pages = {119, [23] S. : graph.
