| Abstract: | Exchange bias measurement techniques are tested using an Ising model for exchange-coupled
bilayer structures. In the presence of hysteresis loop asymmetry, the conventional exchange bias
characterization method of measuring the sum of the coercive fields is found to be rather inaccurate
if compared to the interface coupling energy. An alternative method based on the analysis of entire
hysteresis loops is proposed, tested, and found to be substantially more robust. |
