The layered honeycomb magnet α-RuCl 3 has been proposed as a candidate to realize a
Kitaev spin model with strongly frustrated, bond-dependent, anisotropic interactions …

Applied magnetic fields underlie exotic quantum states, such as the fractional quantum Hall
effect and Bose–Einstein condensation of spin excitations. Superconductivity, however, is …

Spin and orbital quantum numbers play a key role in the physics of Mott insulators, but in
most systems they are connected only indirectly—via the Pauli exclusion principle and the …

The literature of low‐dimensional CuII molecular magnetic systems in which superexchange
pathways involve halide ions and/or cyclic 1, 4‐diazines is reviewed. Compounds are …

MnBi 2 Te 4 (MBT) materials are promising antiferromagnetic topological insulators in which
field-driven ferromagnetism is predicted to cause a transition between axion insulator and …

We present thermodynamic studies of a new spin-1/2 antiferromagnet containing undistorted
kagome lattices—barlowite Cu 4 (OH) 6 FBr. Magnetic susceptibility gives θ CW=-136 K …

Strong electronic interactions in condensed-matter systems often lead to unusual quantum
phases. One such phase occurs in the Kondo insulator YbB12, the insulating state of which …

We apply a strong magnetic field to a kagome Mott insulator with antiferromagnetic
interactions which does not show magnetic ordering down to low temperatures. We observe …

We present evidence of magnetic order in the quasi-one-dimensional spin-1/2 molecular
chain compound, copper pyrazine dinitrate Cu (C 4 H 4 N 2)(NO 3) 2. Zero field muon-spin …

The accurate electron density distribution and magnetic properties of two metal–organic
polymeric magnets, the quasi-one-dimensional (1D) Cu (pyz)(NO3) 2 and the quasi-two …
