ABSTRACT Thin films of the molecular magnet Mn12-acetate, [Mn12O12(CH3COO)16(H2O)4]·2CH3COOH·4H2O, have been prepared using a laser ablation technique with a nitrogen laser at low laser energies of 0.8 and 2mJ. Chemical and magnetic characterizations show that the Mn12-acetate cores remain intact and the films show similar magnetic properties to those of the parent molecular starting material. In addition, the magnetic data exhibit a peak in the magnetization at 27K indicating the creation of an additional magnetic phase not noted in previous studies of crystalline phases.
