Microscopic Origin of Random Singlet Behavior in B-site Disordered Spin-1/2 Perovskite BaCu_1/3Nb_2/3O_3 Revealed by EXAFS and Thermodynamics

Sagar Mahapatra, Francesco De Angelis, Martin Etter +5

We report a combined structural and thermodynamic study of the ABO $_{3}$ -type disordered perovskite BaCu $_{1/3}$ Nb $_{2/3}$ O $_{3}$ (BCNO), whose B site is jointly occupied by Cu and Nb…

Emergent Random Spin Singlets in Disordered Spin-1/2 perovskite BaCu $_{1/3}$ Ta $_{2/3}$ O $_{3}$

Sagar Mahapatra, Francesco De Angelis, Dibyata Rout +8

We investigate the disordered perovskite BaCu $_{1/3}$ Ta $_{2/3}$ O $_{3}$ , where Cu (spin-1/2) and Ta randomly occupy a pseudo-cubic lattice. Synchrotron X-ray diffraction and X-ray abs…

Origin of magnetic moments and presence of a resonating valence bond state in Ba $_{2}$ YIrO $_{6}$

Abhishek Nag, Sayantika Bhowal, M. M. Sala +10

While it was speculated that 5 $d^{4}$ systems would possess non-magnetic $J$ ~=~0 ground state due to strong Spin-Orbit Coupling (SOC), all such systems have invariably shown presence…
