Abstract
The Everett function is a widely used tool to evaluate the output of scalar Preisach hysteresis
operators. Compared to a matrix-based implementation, the Everett function does not only allow a
stageless evaluation of the switching state but, furthermore, reduces the required storage to a single
list of dominant input minima and maxima. To deal with magnetic fields that change direction over
time, a vector extension of the scalar Preisach model based on rotational operators can be utilized.
This straight-forward extension enables an efficient description of vector hysteresis phenomena. Due
to the dependency between the newly added rotational operator and the original switching operator,
neither the usage of a single list nor the direct application of the Everett function is possible. In this
contribution, we propose a nested-list data structure for the vector Preisach model based on rotational
operators. Exploiting this data structure allows the usage of an adapted Everett function and, thus, an
efficient, stageless representation of both the rotational operator as well as the switching operator.
