Abstract
It is well known that small particles of ferromagnetic material show superparamagnetic behavior. The magnetic properties of hematite, which has a weak spontaneous magnetization show superparamagnetic behavior in grains which are as large as 1/4 to 1/2 μ in diameter. This is shown to be the case by the use of magnetic tests, including hysteresis and Curie temperature effects and by the use of X-ray diffraction and optical determination of particle sizes.
