The magnetic ground states of rare-earth frustrated magnets can be governed by competing energy scales arising from crystal-field anisotropy, exchange interactions, and long-range dipolar interactions. Here we investigate this interplay in the triangular-lattice antiferromagnet NaBaEr(BO$_3$)$_2$ by combining magnetiza...

Lithium cobalt oxide (LiCoO2, LCO) is one of the most successful cathodes. However, it suffers from severe structural degradation and rapid capacity fading at high voltage (>4.5 V vs. Li+/Li). To improve high-voltage stability, researchers employ channel-type materials to desolvate lithium ions, resulting in a localize...

Eliminating platinum group metals from cathode catalysts in low-temperature polymer electrolyte fuel cells is highly important for addressing the sustainability challenge fuel cell systems face. Here, we propose modifying the electronic structure of Li-intercalated layered Mn-oxide as a cathode catalyst to overcome...
