ESR in dilute quasi 2-dimensional Mn stearate

Quasi 2-dimensional (2d) magnets of manganese stearate diluted with cadmium stearate were prepared by the LangmuirBlodgett technique. Anisotropies of ESR line-widths were analyzed into components dominated by exchange and spin diffusion. An anomoly in the spin diffusion component was observed near the percolation limit. © 1980.
