In transition-metal compounds with partially filled 4 d and 5 d shells spin–orbit
entanglement, electronic correlations, and crystal-field effects conspire to give rise to a …

Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm
in length) and possibly even nanoplastics (< 1 μm) has recently raised health concerns. In …

Recently, Co-based honeycomb magnets have been proposed as promising candidate
materials to host the Kitaev spin liquid (KSL) state. One of the front-runners is BaCo2 (AsO4) …

Quantum spin liquids (QSLs) are topologically ordered states of matter that host
fractionalized excitations. A particular route towards a QSL is via strongly bond-dependent …

Na 2 Co 2 TeO 6 is a proposed approximate Kitaev magnet, yet its actual magnetic
interactions are elusive due to a lack of knowledge on the full excitation spectrum. Here …

As a candidate Kitaev material, Na 2 Co 2 TeO 6 exhibits intriguing magnetism on a
honeycomb lattice that is believed to be C 3 symmetric. Here we report a neutron diffraction …

High-spin d 7 Co (II) compounds have recently been identified as possible platforms for
realizing highly anisotropic and bond-dependent couplings featured in quantum-compass …

Cobaltates with 3 d based layered honeycomb structure were recently proposed as Kitaev
magnets and putative candidates to host the long-sought Kitaev spin liquid. Here we present …

The magnetic structures and spin dynamics of Na 2 Co 2 Te O 6 and Na 2 Ni 2 Te O 6 are
investigated by means of elastic and inelastic neutron scattering measurements and the …
