anisotropy constant
High Magnetic Anisotropy Materials. Takao Suzuki . MINT Center. MINT Seminar (2/6/2015) 1 The shape of an M(H) curve may depend on many things. The anisotropy constant is only one of them. Especially you would want to know the mechanism by which the magnetization is reversed - several possibilities exist and each of them produces its own version of what the M(H) curve looks like. Some of these quantities are dose rate constant, radial dose function, anisotropy function, anisotropy factor, and geom-etry factor. Recommended values of dosimetry constants would result in changes of up to 17% in the dosimetry of interstitial brachytherapy sources. A qualified brachytherapy Medical Physics, Vol. 22, No. 2, February 1995 Crystal anisotropy constant gives the difference between magnetizing the crystal in easy direction (100) and hard direction (111). The formula to find anisotropic constant is Mα Tc = constant. Here, Mα is anisotropic constant and Tc is critical temperature. Tc is the temperature below which the substance becomes a superconductor. Uniaxial anisotropy constant Ku for (a) c/a=1.25 and (b) c/a=1.15 as. A function of Co content x.

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: All Answers (11) 1  See for example J. M. D.

Summary MINT Seminar (2/6/2015) 2 What is the anisotropy constant and its use? And how can I find the anisotropy constant from magnetic data? I want to calculate the anisotropy constant from the M-H Loop.
