    Abstract
    In this paper, we develop circuit models for spintronic devices that are under the application of electric and magnetic fields. Starting from time-dependent drift-diffusion equations in nonmagnets and ferromagnets, we spatially and temporally discretize the resulting current-voltage relations using linear multistep methods, which yield equivalent circuit models characterized by finite-difference versions of the so-called 4 × 4 conductance matrices. By using a time-dependent formulation, introducing a new model for ferromagnets, and including ubiquitous effects such as spin dissipation, spin precession, as well as thermal noise, our model serves as a framework to unify and expand the existing models in the literature. To demonstrate our model's utility in applications, we performed simulations on several spintronic devices and validated the results against simulated and measured data. We also discuss extensions to the model and general directions for the future research.

    Export search results

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items. For anonymous users the allowed maximum amount is 50 search results.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
