Spin splitting of dopant edge state in magnetic zigzag graphene nanoribbons

Decoupling spin-polarized edge states using substitutional N-atom dopants along the edges of a zigzag graphene nanoribbon (ZGNR) reveals giant spin splitting of a N-dopant edge state, and supports the predicted emergent magnetic order in ZGNRs.

Confinement of atomically defined metal halide sheets in a metal–organic framework

The pore space in the metal–organic framework Zr₆O₄(OH)₄(bpydc)₆ can be used as a scaffold to grow precisely defined atomically thick sheets of metal halide materials, taking advantage of multiple binding sites to direct complexation of the metal ions; these metal halide nanosheets fill the size gap between discrete molecular magnets and bulk magnetic materials, with potentially unusual magnetic properties arising from this size regime.

Deciphering chemical order/disorder and material properties at the single-atom level

The three-dimensional coordinates of more than 23,000 atoms in an iron-platinum nanoparticle are determined with 22 picometre precision to correlate chemical order/disorder and crystal defects with magnetic properties.

Enhancing coherence in molecular spin qubits via atomic clock transitions

Magnetic molecules are candidates for solid-state spin qubits from which a quantum computer might be constructed, but the magnetic interactions between such molecules typically lead to unwanted decoherence; now magnetic molecules have been designed in such a way that their spin dynamics are energetically protected against the decoherence-inducing interactions.

Designing switchable polarization and magnetization at room temperature in an oxide

Ferroelectricity and ferromagnetism are combined in a bulk perovskite oxide at room temperature by constructing a percolating network of interacting magnetic ions within a complex polar solid.

Beating the Stoner criterion using molecular interfaces

By harnessing the charge transfer that takes place at the interface between a metal and a layer of molecules, the usually non-magnetic materials copper and manganese are made magnetic at room temperature.

Structural insight into magnetochrome-mediated magnetite biomineralization

The magnetosome-associated protein mamP is an iron oxidase that reveals a unique arrangement of a self-plugged PDZ domain fused to two magnetochrome domains, defining a new class of c-type cytochrome exclusively found in magnetotactic bacteria.
