Dependence of the magnetization and remanence of single-domain particles on the second cubic anisotropy constant
(2001) [Artigo de periódico]Magnetization and remanent magnetization curves for noninteracting single-domain particles with cubic magnetocrystalline anisotropy have been calculated, taking into account the first two anisotropy constants. The dependencies ... -
Inhomogeneous structure and magnetic properties of granular Co/sub 10/Cu/sub 90/ alloys
(2001) [Artigo de periódico]Granular Co₁₀Cu₉₀ alloys displaying giant magnetoresistance have been obtained by melt spinning followed by an appropriate heat treatment in the range 0–700 °C. Their structural and magnetic properties have been studied ... -
Phase evolution and magnetic properties of a high-energy ball-milled hematite-alumina system
(2004) [Artigo de periódico] -
Remanent magnetization plots of fine particles with competing cubic and uniaxial anisotropies
(1999) [Artigo de periódico]Magnetization and remanent magnetization curves for noninteracting single-domain particles whose anisotropy is made up of a cubic magnetocrystalline and an uniaxial components were investigated. For a given cubic anisotropy, ... -
Tuning the ferromagnetic-antiferromagnetic interfaces of granular Co-CoO exchange bias systems by annealing
(2014) [Artigo de periódico]The low-temperature magnetic behavior of granular Co-CoO exchange bias systems, prepared by oxygen ion implantation in Co thin films and subsequent annealing, is addressed. The thermal activation effects lead to an O ...
