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.

This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Vacancy‐Controlled Lattice Dynamics and Magnetism in Mn‐Doped CeO2−δ Nanocrystals
ABSTRACT Mn‐doped CeO2−δ${\rm CeO}_{2-\delta }$ nanocrystals provide a model system to quantify how defect chemistry controls emergent magnetism in a wide‐gap oxide. Single‐phase fluorite Ce1−xMnxO2−δ${\rm Ce}_{1-x}{\rm Mn}_x{\rm O}_{2-\delta }$ (0≤x≤0.09$0 \le x \le 0.09$) nanocrystals exhibit nonmonotonic changes in lattice parameter, microstrain ...

Structural, Superconducting and Magnetic Properties of Oxygen‐Annealed Fe1+yTe Thin Films
FeTe:Ox films exhibit exchange bias below their Néel temperatures, which coexists with superconductivity. STEM analysis reveals the structural changes induced by oxygen treatment. DFT calculations indicate that interstitial oxygen suppresses antiferromagnetism and promotes superconductivity.

The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.
