Micromagnetics of shape anisotropy based permanent magnets

Prospects for nanoparticle-based permanent magnets

Magnetic nanoparticles smaller than ~15 nm in diameter and with high magnetocrystalline anisotropies K1 ≥ 1 MJ m can be used as building blocks for next-generation permanent magnets. Advances in processing steps are discussed, such as self-assembly, alignment of the easy axes and appropriate nanostructuring that will enable the fabrication of densely packed nanoparticle assemblies with improved...

Spatial detection of ferromagnetic wires using GMR sensor and based on shape induced anisotropy

The purpose of this paper is to introduce a new technique for row spacing measurement in a wire array using giant magnetoresistive (GMR) sensor. The self-rectifying property of the GMR-based probes leads to accurately detection of the magnetic field fluctuations caused by surface-breaking cracks in conductive materials, shape-induced magnetic anisotropy, etc. The ability to manufacture probes h...
