Entry into a new class of tetra- and dicopper clusters was assisted by a fine steric tuning of bulky amidinate ligands that provide spin-delocalizing superexchange pathways in class III mixed-valence clusters, the properties of which are best understood without invoking metal-metal bonding.

To achieve scalable quantum information processing, great efforts have been devoted to the creation of large-scale entangled states in various physical systems. Ultracold atom optical lattice is considered as one promising platforms due its feasible initialization and parallel manipulation. In this work, we propose an efficient scheme generate characterize global entanglement lattice. With only...

Abstract A comprehensive x‐ray scattering study of spontaneous magnetostriction in hexagonal MnTe, an antiferromagnetic semiconductor with a Néel temperature T N = 307 K, is presented. The largest magnetovolume effect known for antiferromagnet observed, reaching volume contraction |Δ V / | > 7 × 10 −3 . This can be justified semiquantitatively by considering bulk material properties, the spa...

An antiferromagnet offers many important functionalities such as opportunities for electrical control of magnetic domains, immunity from perturbations, and fast spin dynamics. Introducing some these intriguing features an into a low dimensional semiconductor core–shell nanowire exciting pathway its usage in antiferromagnetic spintronics. Here, using quantum mechanical approach, we predict that ...

Abstract W-hexaferrite BaCo 2 Fe 16 O 27 was prepared using the citrate nitrate combustion method. The sample characterized XRD, SEM, EDX and elemental mapping. XRD confirmed that synthesized in a single phase hexagonal structure with an average crystallite size 37.39 nm. SEM images of show spongy morphology agglomerated grain owing to dipole interaction between crystallites. magnetic propertie...
