Possibility of a correlation-spectroscopy study of small ferromagnetic particles
Berkov D. V., Manykin E. A., Sakipov N. Z.
Small ferromagnetic particles can be studied by a method of correlation spectroscopy. The dispersion of small superparamagnetic particles of Fe304 has been studied. Measurements of the correlation function of the light intensity scattered by this system have made it possible to determine the spontaneous magnetization-reversal time and also the anisotropy constant of the particles over the conventional method for studying superparamagnetism—Mossbauer spectroscopy—are discussed.
