“…As no single method can provide complete and accurate information on the mineral magnetic properties of the sample, several techniques have been used in this study. The type of magnetic minerals (remanence carriers), their concentration, and domain states are important factors in determining the reliability of the results found in the artifacts [1][2][3][4]. The artifacts are subjected to rock magnetic studies like magnetic susceptibility (frequency) and isothermal remanent magnetisation (IRM) acquisition in order to characterise the main magnetic phases and to select the most suitable samples for paleointensity measurements.…”

This study investigates the magnetic mineralogy of a collection of archaeological potteries. Actual magnetic carriers and the domain states of the constituent magnetic fine particles have been obtained from the acquisition of isothermal remanence and low field susceptibility measurements. The magnetic mineralogy of all samples has been dominated by ferrimagnetic mineral (magnetite/magnetite with low titanium content) which is suitable for paleointensity measurement in determining the intensity of the ancient geomagnetic field.
