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…

Susceptibility anisotropy and absence of ferroelectric order in the Kitaev spin liquid candidate Na $_{2}$ Co $_{2}$ TeO $_{6}$

C. Dhanasekhar, Monika Jawale, Rahul Kumar +6

We report the magnetic, magnetodielectric, and electric polarization properties of single crystals of the Co-based Kitaev Spin Liquid (KSL) candidate Na $_{2}$ Co $_{2}$ TeO $_{6}$ (NCTO). Th…
