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…

Half-metallicity and wandering axis ferromagnetism in Fe $_{2}$ Ti $_{1 - x}$ Mn $_{x}$ Sn (0 $< x \leq$ 0.3) Heusler Alloys

Kulbhushan Mishra, Shishir Kumar Pandey, S. Chaudhuri +2

We investigate the effect of Mn substitution in Fe $_{2}$ Ti $_{1 - x}$ Mn $_{x}$ Sn on electronic structure and magnetic and electrical transport properties. The spin-polarized density of sta…
