The authors present possibilities of the engineering of magnetic properties (e.g. magnetic anisotropy and coercivity field) of nanostructures during deposition processes and post growth treatments, e.g. by ion irradiation and laser annealing. Magnetization distributions in single ultrathin layer and multilayers have been studied both experimentally (using Co films sandwiched between Au, Pt or Mo layers) and theoretically. These huge distribution changes, driven by nanostructure geometry or magnetic field, are shown.

The measurements of critical temperature and critical magnetic fields were carried out in superconducting Ni/Pb modulated films. These films consisted of thick Pb component layers (dpb = 400 Å) and thin layers of Ni with thickness dNi ranging from 8 Å to 30 Å. The dependence of critical temperature on the thickness of Ni component layers was compared with theoretical model. Our measurements of parallel critical field as a temperature function did not give any evidence of dimensional crossover of superconductivity induced by temperature.

Magnetization distributions in ultrathin magnetic either single layers or multilayers might be manipulated by: the thickness of the magnetic layers, the thickness of the nonmagnetic either cap/buffer or spacer layers, magnetic anisotropy and geometrical confinement of the system. Such layers are very promising candidate as a material for e.g. high‐density storage media. But one of the challenges is to find a method which allows to perform a precise and controlled manipulation of the properties. Very recently it has been discovered in ultrathin magnetic films that both the magnetization distribution and the critical thickness of a magnetization reorientation phase transition between perpendicular and in‐plane states, can be also controlled by the post‐growth treatments, e.g. by either ion or light irradiation. The cover image shows the example of a two‐dimension diagram of the polar Kerr rotation angle remanence versusultrathin Co thickness and Ga+ion fluence. The non‐irradiated region is marked as the “reference”. Regions with zero remanence correspond to: (i) in‐plane magnetization orientation (blue area) and (ii) superparamagnetic properties (magenta area). The regions with enhanced magneto‐optical effects correspond to out‐of‐plane magnetization states. The irradiation induces two branches of out‐of‐plane magnetization states. Magnetization distributions in single ultrathin layer and multilayers have been studied both experimentally and theoretically. The huge changes of these distributions, driven by the nanostructure geometry or magnetic field, are discussed in the Feature Article by Maziewski et al. (pp. 1005–1018). The irradiation‐induced effects open novel routes for both tailoring thin‐film magnetic and magneto‐optical properties and patterning of magnetic nanostructures.

We have investigated vibrational modes of C60monolayer film adsorbed on the Si(111)7×7 surface using high-resolution electron-energy-loss spectroscopy in combination with scanning tunneling microscopy. The differences in energies and in oscillator strengths from a thick C60film (i.e., bulk C60) are discussed in terms of the charge transfer from silicon dangling bonds to C60molecules. The amount of charge transfer is estimated to be 1±1 electron(s) compared with the infrared absorption spectra of alkaline-doped C60fullerides and with the weak electron-molecular-vibration coupling calculation.
