New York: Cambridge University Press, 2010. 2  The anisotropy constant expresses a measure of how different the longitudinal magnetization is from the transverse magnetization for an anisotropically magnetized medium. For a more precise definition look in the book suggested by Sergey. For an easier definition and a method for driving it from magnetization data look at these two papers:
