Book Description
The Symposium on Magnetic Ultrathin Films, Multilayers and Surfaces, hosted by the European Materials Research Society, was held at the Palais de la Musique et des Congré in Strasbourg, France on June 4-7, 1996. Its central theme was the relationship of magnetic properties and device performance to structure at the nano and micrometer length scale. Research on the magnetism of surfaces, ultrathin films and multilayers has increased dramatically during recent years. This development was triggered by the discovery of coupling between ferromagnetic layers across nonmagnetic spacer layers and of the giant magnetoresistance effect in systems of reduced dimension using various micro and nanofabrication techniques has become a subject of special interest. It is certainly the promising application potential of these effects in new magnetic recording device geometries which causes this intensive research, which is done both by companies and at universities and research institutes. A selection of invited and contributed papers presented at the Symposium and accepted for publication is contained in this volume. The contents of these proceedings are organized into seven sections. A. Nanowires, Nanoparticles, Nanostructuring B. Ultrathin Films and Surfaces, Characterization C. Giant Magnetoresistance D. Coupling, Tunneling E. Growth, Structure, Magnetism F. Growth, Structure, Magnetoresistance G. Coupling, Magnetic processes, Magneto-optics. The first four sections contain invited and oral contributed papers in the listed research domains, while the last three sections contain the contributions presented during three large poster sessions.

Book Description
This thesis focuses on the study of ferromagnetism in Dilute Magnetic Oxides. To investigate the origin of ferromagnetism, magnetic, optical, magneto-optical properties are intensively explored. These techniques have also been applied to investigate the presence of metallic nanoparticles in these oxides. Non-interacting particle model which can be applied to fit the results of hysteresis, and an alternative method of structural characterisation using EXAFS, Maxwell-Garnett (M-G) theory, which is very sensitive for estimating the volume fraction of nanoparticles in the sample, are demonstrated. A model is suggested to explain the observed ferromagnetism in Co-doped ZnO thin films; this includes the contribution from nanoparticles, the oxide host and the exchange coupling between these two components. A grain boundary model is suggested to explain the observed ferromagnetism in Fe-, Mn-, and V-doped In2O3 thin films which were prepared by the PLD technique. Intrinsic defects in the samples play an important role in determining the ferromagnetism but are not the only source, as is demonstrated by sequential anneal in vacuum and air. This work is expected to shed some light on the origin of ferromagnetism in oxide systems.

Book Description
Materials Research in thin and ultrathin magnetic structures is a multidisciplinary field which heavily relies on state-of-the-art growth, characterization and theoretical approaches to build a comprehensive physical picture on how magnetic properties depend on interfacial structural issues, interlayer coupling and transport phenomena. Often in this field, the critical properties and characterization required necessitates knowledge of structural and magnetic phenomena extending over several atomic planes. Atomic controlled growth techniques are required and atomic sensitivity is needed from magnetic and structural probes. This critical knowledge is vital for device applications, providing the basis for the synergistic interactions that are predominant in this field of research. This volume is the definitive reference source for anyone interested in the latest advances and results of current experimental research in ultrathin film magnetism.
