Fast and universal approach for quantitative measurements of bistable hysteretic systems

Accurate and fast characterization of hysteretic systems can accelerate progress in fields as diverse as biomedicine, sensors, data storage, and logic devices. Here, we introduce a fast approach to determine magnetic parameters (intrinsic coercivities of elementary domains, interaction fields between the domains, and the variances of both) of bistable hysteretic systems. The approach uses the first few points in first-order reversal curves...
