It has been challenging to design multifunctional lead-free organic–inorganic hybrid halides
that can exhibit fascinating magnetic and photoluminescence properties since the …

We use temperature dependent neutron powder diffraction (NPD) to investigate the
structural changes and magnetic interactions in double perovskite Sr2–x La x CoNbO6 (x …

The Bi3FeMo2O12 system is examined as a rare example of a transition-metal oxide which,
upon heating, undergoes a symmetry lowering and a 2: 1 ordering of the transition-metal …

One-dimensional (1D) Heisenberg antiferromagnets are of great interest due to their
intriguing quantum phenomena. However, the experimental realization of such systems with …

We prepared a new polar layered quantum magnet Ba2Cu3 (SeO3) 4F2, by a combined use
of F–and pyramidal SeO32–anions, determined its crystal structure by X-ray diffraction, and …

Conspectus In both inorganic and metal–organic compounds, transition metals surrounded
by ligands form regular or distorted polyhedra, which can be either isolated or …

We investigate the properties of a frustrated spin-5/2 chain with next-nearest-neighbor two-
and three-site interactions, with two questions in mind: the nature of the transition into the …

Isolated large-spin Heisenberg antiferromagnetic uniform chain is quite rare. Here, we have
successfully synthesized an ideal one-dimensional (1D) S= 5/2 linear-chain antiferromagnet …

The frustrated spin-chain (FSC) systems exhibit exotic ground states and distinct quantum
phase transitions. The S= 1 2 FSC is known to exhibit the Kosterlitz-Thouless transition from …

We study the nature of quantum phase transitions out of $\mathbb {Z} _4 $ ordered phases
in quantum loop models on a zig-zag ladder. We report very rich critical behaviour that …
