Empirical scaling law (EPSL, 226, 521-528, 2004) revealed a fundamental
linear magnetic relation capable of revealing the magnetizing field
during either thermal and/or chemical magnetic remanence acquisition
measured at room temperature. Power law relationship with exponent tied
to demagnetizing field that is both magnetic minerals and/or shape
dependent. Paleointensity vector estimate is done with using the
measurement of efficiency of ratios between natural remanent and
saturated remanent magnetizations at demagnetized (by alternating
magnetic fields) to monotonously increasing levels up to 100 mT.
Combining empirical law with the spectrum of alternating-field sample
demagnetization allows not only unique view into the history of magnetic
fields that were present during the history of the sample but also
ability to group the magnetic carriers within sample according to their
magnetic resistance towards AF demagnetization. We show how
paleomagnetic field can be detected by using this method in Murchison
meteorite samples, samples affected by magnetic field from lightning,
discharge and geomagnetic field recorded in glass samples of various
origins.
