Scientific paper

It is shown that mixed MgO FeO SiO grains should be superparamagnetic or weakly ferromagnetic. The resulting enhancement in magnetic susceptibility implies that grains with radii of 0.1 to 0.3 micron and icy mantles on MgO FeO SiO cores can be aligned in magnetic fields of no more than 1 microgauss. In both cases alignment occurs through the Davis and Greenstein mechanism with an enhancement in the imaginary component of magnetic susceptibility owing to spin-lattice relaxation for ferromagnetic cores and to superparamagnetic relaxation for superparamagnetic cores.
