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-type disordered perovskite BaCuNbO (BCNO), whose B site is jointly occupied by Cu and Nb…
Spin-orbit-entangled frustrated magnetism in fcc Ba(Yb,Nd)NbO double perovskites
S. M. Hossain, Sk. Soyeb Ali, S. Mohanty +7
The search for candidate Kitaev materials has largely focused on 4 and 5 transition-metal compounds with various lattice geometries. In contrast, investigations of rare-earth…
Crystal electric field excitations and spin dynamics in a spin-orbit coupled distorted honeycomb magnet BiErGeO
S. Mohanty, S. Guchhait, S. S. Islam +9
The magnetic properties and crystal electric field (CEF) scheme of BiErGeO are investigated via magnetization, heat capacity, muon spin relaxation (muSR), and inelastic neutron…
Emergent Random Spin Singlets in Disordered Spin-1/2 perovskite BaCuTaO
Sagar Mahapatra, Francesco De Angelis, Dibyata Rout +8
We investigate the disordered perovskite BaCuTaO, where Cu (spin-1/2) and Ta randomly occupy a pseudo-cubic lattice. Synchrotron X-ray diffraction and X-ray abs…
