【 摘 要 】

Thin films of the molecular magnet Mn-12-acetate, [Mn12O12(CH3COO)(16)(H2O)(4)](.)2CH(3)COOH(.)4H(2)O, have been prepared using a laser ablation technique with a nitrogen laser at low laser energies of 0.8 and 2 mJ. Chemical and magnetic characterizations show that the Mn-12-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.
