Abstract: The compounds composed of transition meatal cations and pnictide anions provide a rich platform for novel physical phenomena. Here we report the observation of a phase transition at ~ 70 K and 145 K from… read more here.

DOI: 10.1103/physrevmaterials.5.014410
Abstract: The rhombohedral distortion-driven occurrence of the spontaneous electric polarization at a reasonably high temperature $(T)$ and an exchange bias (EB) effect below the antiferromagnetic (AFM) N\'eel temperature $({T}_{N})$ are revealed in ${\mathrm{ZnFe}}_{2}{\mathrm{O}}_{4}$. We observe the… read more here.

DOI: 10.1109/tip.2020.2983849
Abstract: In this work, we propose an overcomplete representation of multiview imagery for the purpose of compression. We present a rate-distortion (R-D) driven approach to decompose multiview datasets into two additive parts which can be interpreted… read more here.
