Magnetic properties of some beach sand ilmenite particles
Samples of naturally occurring beach sand ilmenite from Swansea, New South Wales, and Capel, Western Australia, were used; in general, magnetic properties were independent of grain size for grains larger than about 10 μ; oxidizing ilmenite in air at temperatures between 700 and 750 C leads to more magnetic form of ilmenite, while annealing these samples further enhances their magnetic properties; samples which were heated in excess of 800 C were nonmagnetic; measurement of induced thermoremanent moment in selected samples allows domain configuration to be postulated.
