  • Grain-size dependent demagnetizing factors in permanent magnets 

    Bance, S; Seebacher, B; Schrefl, T; Exl, L; Winklhofer, M; Hrkac, G; Zimanyi, G; Shoji, T; Yano, M; Sakuma, N; Ito, M; Kato, A; Manabe, A (American Institute of Physics (AIP), 2014)
    The coercive field of permanent magnets decreases with increasing grain size. The grain size dependence of coercivity is explained by a size dependent demagnetizing factor. In Dy free Nd$_2$Fe$_{14}$B magnets the size ...
  • High energy product in Battenberg structured magnets 

    Bance, S; Oezelt, H; Schrefl, T; Winklhofer, M; Hrkac, G; Zimanyi, G; Gutfleisch, O; Evans, RFL; Chantrell, RW; Shoji, T; Yano, M; Sakuma, N; Kato, A; Manabe, A (American Institute of Physics (AIP), 2014-11-10)
    © 2014 AIP Publishing LLC. Multiphase nano-structured permanent magnets show a high thermal stability of remanence and a high energy product while the amount of rare-earth elements is reduced. Non-zero temperature micromagnetic ...
  • Influence of defect thickness on the angular dependence of coercivity in rare-earth permanent magnets 

    Bance, S; Oezelt, H; Schrefl, T; Ciuta, G; Dempsey, NM; Givord, D; Winklhofer, M; Hrkac, G; Zimanyi, G; Gutfleisch, O; Woodcock, TG; Shoji, T; Yano, M; Kato, A; Manabe, A (American Institute of Physics (AIP), 2014)
    The coercive field and angular dependence of the coercive field of single-grain Nd$_{2}$Fe$_{14}$B permanent magnets are computed using finite element micromagnetics. It is shown that the thickness of surface defects plays ...
