The magnetic interactions in arrays of nanometer-scale ferromagnetic iron particles enhanced by direct growth onto thin permalloy films were investigated. The magnetic measurements [Hall magnetometry up to 100 K and variable field MFM (magnetic force microscopy) at room temperature] showed that the magnetization behavior of the permalloy was strongly influenced by the presence of the small (∼13 nm in diameter) particles. The mean values of the particles' switching fields coincided with those for noninteracting particles. The switching field distribution of the iron particles, however, was considerably broadened by their interactions. These results for strongly interacting small particles exemplify the magnetization behavior of ever smaller and more dense magnetic storage media. © 2000 American Institute of Physics.
