Structure Evolution of NdF3 Optical Thin Films

The structure evolution characteristics of NdF3 thin films has been analysed concerning texture and grain morphology. The structure could be classified according to the structure zone models, and the growth mode could be related to zone T and zone II. Contamination of the films by residual gases was found to inhibit the migration of grain boundaries and therefore, zone II does not appear even a...

Topological defects, pattern evolution, and hysteresis in thin magnetic films

– The nature of the magnetic hysteresis for thin films is studied by the Monte Carlo simulations. It is shown that a reconstruction of the magnetization pattern with external field occurs via the creation of vortex-antivortex pairs of a special kind at the boundaries of stripe domains. It is demonstrated that the symmetry of the order parameter is of primary importance for this problem, in part...

Hard Magnetic Thin Films

Hard magnetic films have a broad application area ranging from magnetic recording media to microelectromagnetic devices. A challenge for recording media is the 60% annual increase in areal density, which requires ever smaller magnetic dots. However, for a given magnetic anisotropy the reduction of dot size is limited, since below a critical magnetic volume the magnetisation becomes thermally un...

Magnetic properties and structure of Fe/Pt thin films

The structural transfqmation from fcc to fct and relevant magnetic properties of initially multilayered Fe/Pt films were studied. When the asdeposited FePt films were annealed at the temperature of 300°C and up, the fct-phase was formed. Rather square hysteresis loops and large coercivities were measured from the annealed films. The films annealed at 300°C retain a layered structure.
