The Demagnetization Field of Multidomain Grains

  • Chapter
Origin of Thermoremanent Magnetization

Part of the book series: Advances in Earth and Planetary Sciences ((AEPS,volume 1))

Abstract

The demagnetization ‘constant’, N, enters into all theoretical considerations of multidomain remanence. Although most workers believe N to be related simply to the shape of the grain, no theoretical study of N has previously been completed. It is shown in this paper thatN monotonically increases with increase in remanence in multidomain grains. Although N can be approximated by a constant in the limit of small displacements of domain walls from their demagnetized sites, this constant critically depends on the domain geometry.
