Inrecentyears, anew?eldinsciencehasbeengrowingtremendously, i. e., theresearch on nanostructures. In the early beginning, impetus came from different disciplines, like physics, chemistry, and biology, that proposed the possibility of producing str- turesinthesub-micronrange. Theworldwideoperatingelectroniccompaniesrealized that this would open up new ?elds of application, and they proposed very challe- ing projects for the near future. Particularly, nanomagnetism became the focus of new concepts and funding programs, like spintronics or magnetoelectronics. These new concepts created a strong...
