The method of forming a magnetic material for ultra-dense magnetic recording media is to form a matrix, which is a nanoscale film composition of FeMnPt alloy, which is layer-by-layer deposited on a substrate of single-crystal SiO2/Si(001). In this case, separate layers of Fe (15 nm) and Pt (15 nm) are deposited with an additional intermediate layer of Mn with a thickness of 7.5 nm
