Non-Fermi liquid behavior in a mixed valent metallic pyrochlore iridate Pb $_{2}$ Ir $_{2}$ O $_{7 - δ}$

Md Salman Khan, Ilaria Carlomagno, Carlo Meneghini +4

Non-Fermi liquid behavior in some fermionic systems have attracted significant interest in last few decades. Certain pyrochlore iridates with stronger spin-orbit coupling strength…

Failure to achieve the $J_{e f f}$ ~=~0 state even in nearly isolated Ir $^{5 +}$ in Sr $_{3}$ NaIrO $_{6}$ : are iridates enough for realizing true $j$ - $j$ coupling?

Abhisek Bandyopadhyay, Atasi Chakraborty, Sayantika Bhowal +11

Spin-orbit coupling (SOC) often gives rise to interesting electronic and magnetic phases in an otherwise ordinary pool of paramagnetic heavy metal oxides. In presence of strong SOC…

Classical Spin Liquid State in the $S = \frac{5}{2}$ Heisenberg Kagomé Antiferromagnet Li $_{9}$ Fe $_{3}$ (P $_{2}$ O $_{7}$ ) $_{3}$ (PO $_{4}$ ) $_{2}$

E. Kermarrec, R. Kumar, G. Bernard +6

We investigate the low temperature magnetic properties of a $S = \frac{5}{2}$ Heisenberg kagomé antiferromagnet, the layered monodiphosphate Li $_{9}$ Fe $_{3}$ (P $_{2}$ O $_{7}$ ) $_{3}$ (PO $_{4}$ ) $_{2}$ ,…

Canted Antiferromagnetic Order in the Kagome Material Sr-Vesignieite

A. Verrier, F. Bert, J. -M. Parent +6

We report $^{51}$ V NMR, $μ$ SR and zero applied field $^{63, 65}$ Cu NMR measurements on powder samples of Sr-vesignieite, SrCu $_{3}$ V $_{2}$ O $_{8}$ (OH) $_{2}$ , a $S = 1/2$ nearly-kagome Heisen…

ARPES study of orbital characters, symmetry breakings and pseudogaps in doped and pure Sr2IrO4

Alex Louat, Benjamin Lenz, Silke Biermann +6

Sr2IrO4 is characterized by a large spin-orbit coupling, which gives rise to bands with strongly entangled spin and orbital characters, called J=1/2 and J=3/2. We use light-polariz…
