Spin-liquid-like ground states in the double hydroxyperovskites CuSn(OD)6 and MnSn(OD)6 evidenced by μSR spectroscopy

Moumita Naskar, Anton A. Kulbakov, Kaushick K. Parui +9

Double hydroxide perovskites with magnetic transition-metal ions were recently identified as a unique class of materials that combine magnetic frustration with correlated proton di…

Evidence of pseudogap and absence of spin magnetism in the time-reversal-symmetry-breaking state of Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$

Florian Bärtl, Nadia Stegani, Federico Caglieris +13

Muon-spin-rotation ( $μ$ SR) experiments and the observation of a spontaneous Nernst effect indicate time-reversal symmetry breaking (BTRS) at $T_{c}^{Z2}$ above the supercon…

Long-range magnetic order in the $S ~ = 1/2$ triangular lattice antiferromagnet KCeS $_{2}$

G. Bastien, B. Rubrecht, E. Haeussler +19

Recently, several putative quantum spin liquid (QSL) states were discovered in $S ~ = 1/2$ rare-earth based triangular-lattice antiferromagnets (TLAF) with the delafossite s…

Impact of disorder on dynamics and ordering in the honeycomb lattice iridate Na $_{2}$ IrO $_{3}$

R. Sarkar, Z. Mei, A. Ruiz +5

Kitaev's honeycomb spin-liquid model and its proposed realization in materials such as $α$ -RuCl $_{3}$ , Li $_{2}$ IrO $_{3}$ and Na $_{2}$ IrO $_{3}$ continue to present open questions about how th…

Local nematic susceptibility in stressed BaFe $_{2}$ As $_{2}$ from NMR electric field gradient measurements

T. Kissikov, R. Sarkar, M. Lawson +10

The electric field gradient (EFG) tensor at the $^{75}$ As site couples to the orbital occupations of the As p-orbitals and is a sensitive probe of local nematicity in BaFe $_{2}$ As$_2…
