Researchers have demonstrated deterministic control of d‑d wave altermagnets by injecting a magnetic octupole current into an altermagnet/normal‑metal bilayer. The resulting magnetic octupole torque flips the Néel vector without any external magnetic field, converting inherently multidomain textures into a single‑domain state. Crucially, the process does not rely on net magnetization or the Dzyaloshinskii–Moriya interaction, broadening its applicability across diverse altermagnetic materials. This breakthrough paves the way for practical, field‑free spintronic components.
Researchers introduced a scalable organic‑inorganic hybrid protective layer of sulfonated poly(ether ether ketone) (SPEEK) and boron nitride nanosheets (BNNS) for aqueous Zn‑ion batteries. The SPEEK‑BNNS interface regulates Zn2+ transport, lowers migration barriers, and mechanically suppresses dendrite formation. In symmetric cells...
Researchers have created the first organic single‑crystal photosynaptic transistors using a hetero‑buckybowl molecule (3S‑2Me).
