Propagating backward-volume spin waves in epitaxial Fe films

AIP Advances, 2022
The propagation characteristics of backward-volume magnetostatic spin-waves in epitaxial Fe(001) films were studied by frequency-domain and time-domain spin-wave propagation spectroscopies using a vector network analyser.

Enhanced High Dimensionality and the Information Processing Capacity in Interfered Spin Wave‐Based Reservoir Computing, Achieved With Eight Detectors

Advanced Electronic Materials, EarlyView.
Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

Finite Size‐Effects in Martensite Microstructure of Magnetic Shape Memory Films

Small, EarlyView.
Magnetic shape memory alloys are a promising multifunctional material system for integration into microsystems. Their multifunctionality arises from the coexistence of ferroelasticity and ferromagnetism. While size‐effects in ferromagnetic microstructure are well understood, corresponding experiments on the ferroelastic microstructure are sparse.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

Advanced 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 ...

Fermilab High Field Option Popae Dipole Magnetostatics [PDF]

IEEE Transactions on Nuclear Science, 1975
Magnetic field computations have been performed for a four-inch coil aperture 45 kG dipole magnet that may be utilized in a high-field option of POPAE. A cold iron version utilizing flat pancake coils has been explored to determine the magnetostatic effectiveness of a simple coil geometry.

Thickness‐Dependent Skyrmion Evolution in Fe3GeTe2 During Magnetization Reversal

Advanced Functional Materials, Volume 36, Issue 18, 2 March 2026.
Thickness‐ and field‐dependent magnetic domain behavior in 2D van der Waals Fe3GeTe2 is studied using Lorentz TEM and micromagnetic simulations. A patch‐like domain phase evolves from skyrmions during magnetization reversal, and step edges between thickness regions act as pinning sites.

Analysis of Magnetic Switching in Magnetically Coupled Dual Free Layers Within Magnetic Tunnel Junctions (MTJ) for STT MRAM

Advanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
A magnetic tunnel junction (MTJ) with two free layers shows four magnetization reversal phases governed by interlayer magnetic coupling (Jcpl). Phase 2 (sequential reversal) reduces write current (Iw) by 50% for 30‐nm‐diameter MTJs compared to Phase 4 (coherent reversal), while Jcpl also boosts thermal stability.
