Extracting Anisotropy Energy Barrier Distributions of Nanomagnetic Systems from Magnetization/Susceptibility Measurements

Anisotropy barrier distributions of single domain particle systems are an important issue in the nanomagnetism and its applications. Different methods to extract the distribution from temperature, field, or time-dependent magnetization/susceptibility are reviewed and compared. A single domain particle system is measured to test the methods. © 2009 Elsevier B.V. All rights reserved
