Like all polarising filters, a circular polariser only transmits light waves with electric and magnetic components of one particular orientation. (newscientist.com)
Internally, the tiny magnetic components in spin ices arrange themselves head to tail in strings, like chains of bar magnets stretching across a table in different directions. (scientificamerican.com)
We will report on the design of Fe3O4 nanoparticles which combine additional magnetic components in order to enhance their magnetic anisotropy through exchange coupling. (european-mrs.com)
