Abstract
Using the applied field angle dependence of the approach to saturation of the magnetization, a theory for the determination of the distribution of easy axes of anisotropy and the ratio between interaction and anisotropy in bidimensional nanomagnetic materials is proposed. The usual saturation process laws in two dimensions at high and intermediate field ranges are recovered and other dependencies between the former are found and justified in terms of scaling arguments. Finally, an approximate analytical model that provides a simpler method by which to determine the easy axis distribution and interaction strength is discussed.
