WebbWe have measured initial susceptibility χ 0 and the dependence of anhysteretic rémanent magnetization (ARM) and thermoremanent magnetization (TRM) on applied field for seven samples of magnetite, with mean grain sizes from 40 to 540 nm. TRM acquisition is nonlinear in geomagnetically relevant weak fields, contrary to the usual assumption …
What does thermoremanent mean? - Definitions.net
Webbthermoremanent: [adjective] being or relating to magnetic remanence (as in a rock cooled from a molten state or in a baked clay object containing magnetic minerals) that indicates the strength and direction of the earth's magnetic field at a former time. Webb26 feb. 2014 · 3 Determination of Cooling Rate Dependency 3.1 Methods. The cooling rate dependency experiments were done at the University of Munich using a bifilar wound vertical dilatometer (DIL 802V) by Baehr for heating and cooling with constant heating/cooling rates.

For synthetic and natural single-domain (SD) magnetites, TRM intensity increases as the cooling rate decreases because a longer exposure time for slower cooling offers more … free checking bank
