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…

Spin-orbit-entangled frustrated magnetism in fcc Ba $_{2}$ (Yb,Nd)NbO $_{6}$ double perovskites

S. M. Hossain, Sk. Soyeb Ali, S. Mohanty +7

The search for candidate Kitaev materials has largely focused on 4 $d$ and 5 $d$ transition-metal compounds with various lattice geometries. In contrast, investigations of rare-earth…

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…

Atypical antiferromagnetic ordering in single crystalline quasi-2D honeycomb magnet YbI $_{3}$

Nashra Pistawala, Luminita Harnagea, Sitaram Ramakrishnan +4

Here, we study YbI $_{3}$ , a quasi-2D layered material with Yb atoms arranged on an ideal honeycomb network of edge-sharing YbI $_{6}$ octahedra, analogous to the low-temperature phase o…
