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…
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…
Role of Disorder in Governing the Magnetic Properties of Cu2IrO3
Priyanka Yadav, Sumit Sarkar, Vishal Kumar +6
CuIrO is a honeycomb iridate which has been studied recently as a candidate Kitaev quantum spin liquid. Its magnetic ground state however, has been reported to be quantum d…
Local Symmetry Breaking in Skyrmion-Hosting Centrosymmetric Hexagonal Compounds
Anupam K. Singh, Krishna K. Dubey, Parul Devi +10
Dzyaloshinskii-Moriya interaction (DMI) plays a crucial role in stabilizing the exotic topologically stable skyrmion spin textures in the noncentrosymmetric crystals. The recent di…
