Operation Regimes and Design Principles of Delta‐E Effect Sensors

open access: yesAdvanced Sensor Research, Volume 5, Issue 4, April 2026.
Delta‐E effect magnetoelectric sensors enable the detection of weak magnetic fields, yet performance optimization remains nontrivial due to coupled magnetic, mechanical, and electronic losses. A systematic study of 24 miniaturized MEMS devices with different geometries reveals three excitation‐dependent regimes: electronic‐noise, magnetic‐noise, and ...

TOPICAL REVIEW: Phase-field modeling of microstructure evolutions in magnetic materials

open access: yesScience and Technology of Advanced Materials, 2008
Recently, the phase-field method has been extended and utilized across many fields of materials science. Since this method can incorporate, systematically, the effect of the coherency induced by lattice mismatch and the applied stress as well as the ...

Modeling Liquid‐Mediated Interactions for Close‐to‐Substrate Magnetic Microparticle Transport in Dynamic Magnetic Field Landscapes

open access: yesParticle &Particle Systems Characterization, Volume 43, Issue 4, April 2026.
The trajectory of a single magnetic particle moving close to a polymer surface in a tailored magnetic field landscape surrounded by a static fluid is quantified using an adjustable simulation model. Varying simulation parameters give insights in key properties of magnetic particle‐based Lab‐on‐a‐chip systems for medical diagnostics.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Cross-over in scaling laws: A simple example from micromagnetics [PDF]

open access: yes, 2002
Scaling laws for characteristic length scales (in time or in the model parameters) are both experimentally robust and accessible for rigorous analysis. In multiscale situations cross--overs between different scaling laws are observed.
