Reliable absolute palaeointensities independent of magnetic domain state

MJ Dekkers, HN Böhnel - Earth and Planetary Science Letters, 2006 - Elsevier
Knowledge of palaeointensity variation is required for determining the full vector variation of
the geomagnetic field as a function of geological time. This provides essential constraints for …

A theoretical treatment of paleointensity determination experiments on rocks containing pseudo-single or multi domain magnetic particles
