Topological Skyrmion‐Based Spin‐Torque‐Diode Effect in Magnetic Tunnel Junctions

open access: yesAdvanced Electronic Materials, EarlyView.
Electrical excitation and detection of a breathing skyrmion in a nanoscale skyrmion‐based spin‐torque diode at room temperature is achieved. Skyrmions are generated via spin‐transfer torque current induction, and their breathing dynamics are observed through ferromagnetic resonance (FMR) measurements.

A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

open access: yesAdvanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.
