Abstract Multi‐electron NAtrium SuperIonic CONductor (NASICON)‐Nb 2 (PO 4 ) 3 (N 0 NbP) is an attractive Na‐ion battery anode, owing to its low intercalation voltage (1.4 V vs Na + /Na and high capacity (≈150 mAh g −1 ). However, it suffers from poor retention due structural degradation. To overcome this issue, extra ions are introduced at the Na(1) sites, via 3+ substitution, which can act as stabilizing agents hold lantern units together during cycling, producing NASICON‐Na 1.5 0.5 Nb...

Sodium superionic conductor (NASICON)-type materials are widely explored as Li- and Na-ion cathodes solid-state electrolytes but largely ignored anodes due to their lower capacities higher intercalation voltages, which reduce the overall energy densities of batteries (LIBs SIBs).

The ground state of $\mathrm{BaF}{\mathrm{e}}_{12}{\mathrm{O}}_{19}$ (BFO) is controversial as three different quantum states, namely, paraelectric, frustrated antiferroelectric, and electric dipole liquid (QEDL), have been proposed. We investigated the critical behavior BFO a function chemical pressure (a nonthermal variable) generated by smaller isovalent ion $\mathrm{C}{\mathrm{a}}^{2+}$ at $\mathrm{B}{\mathrm{a}}^{2+}$ site. Analysis synchrotron x-ray diffraction data confirms that...

Sodium superionic conductor (NASICON)-type cathodes are considered promising candidates for long-cycle-life and high-power Na-ion batteries due to their excellent structural stability mobility. While electrochemical performances have been improved by carbon-coating, particle nanosizing, chemical tuning strategies, the fundamental understanding of impact substitutions is still elusive, which hinders further development. Herein, we explore a series micron-sized...

The magnetic interactions in the multiferroic hexagonal (h-) REMnO3 with RE3+ ions are geometrically frustrated, but only long-range ordering transitions have been reported so far. Using dc and ac susceptibility measurements on well-characterized single crystals of h-DyMnO3, we present here evidence for a spin glass (SG) transition around spin-reordering at TDy3+ ≈ 7 K. This is shown to exhibit history-dependent irreversibility, de Almeida–Thouless line T–H plane, critical slowing down...

The synthesis of multimetal fluorides (MMFs) is challenged by the usage toxic fluoride precursors and their thermodynamic instability at higher temperatures.

We present here the results of low-temperature magnetization and X-ray magnetic circular dichroism studies on single crystals BaFe12O19 which reveal for first time emergence a spin glass phase, in coexistence with long-range ordered ferrimagnetic due to freezing basal plane component.

Evidence is presented for a reentrant quantum paraelectric (QPE) state preceded by dipole glass (DG) phase with nonclassical exponent in the critical regime of $\mathrm{SrF}{\mathrm{e}}_{12}{\mathrm{O}}_{19}$.
