Communication: The choice of optimum treatment for magnetic cleaning- an example

Abstract

Alternating field demagnetization is commonly employed in paleomagnetism (As y Zijderveld, 1958; Coll:nson et al., 1967). Use of existing criterion (e.g., As and Zijderveld, 1958; Irving et al., 1961; McElhinny and Gough, 1963) is largely based on the judgement of the paleomagnetist. This note gives an example to illustrate the choise of optimum treatment for magnetic cleaning.
