1. Effect of post deposition annealing on the hysteresis loops of sputtered NdFeB films

    Journal of Magnetism and Magnetic Materials 272:E877 (2004)

    We have studied the effect of post deposition annealing on the structure and magnetic properties of NdFeB films sputtered on Si (1 0 0) substrate. After annealing the films exhibit hard magnetic properties with room coercivities up to 7.3 kOe and maximum energy product of ...

    Nature 423(6942):850 (2003) PMID 12815426

    Interest in magnetic nanoparticles has increased in the past few years by virtue of their potential for applications in fields such as ultrahigh-density recording and medicine. Most applications rely on the magnetic order of the nanoparticles being stable with time. However, with decreasing part...
