This multispecimen parallel differential pTRM method is based on the
of pTRM with inducing field, a property that is independent of domain
It is much faster than Thellier-Thellier-type experiments, and as long
as no alteration occurs, it can be used for all magnetic grains.
especially for intermediate grain sizes, this method seems to

which the overprinted pTRMs are isolated, an estimate of the domain

only been tested on synthetic specimens.
