Abstract :
Acicular magnetic particles up to about 25 nm thick can be suspended permanently and individually in a liquid. Their orientation by dc and ac magnetic fields can be followed through the induced optical birefringence (Cotton-Mouton effect). Analysis of the field dependencies yields the average magnetic dipole moment of the particles and the width of the distribution, the magnetic anisotropy field, and the distribution of switching fields.
