Spontaneous exchange bias in a nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$

Tuhin Maity, Sudipta Goswami, Dipten Bhattacharya +2

We have observed a large as well as path-dependent spontaneous exchange bias (H $_{S E B}$ ) ( $\sim$ 30-60 mT) in a nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$ across 5-300 K when it i…

Impact of alloy disorder on the band structure of compressively strained GaBiAs

Muhammad Usman, Christopher A. Broderick, Zahida Batool +4

The incorporation of bismuth (Bi) in GaAs results in a large reduction of the band gap energy (E $_{g}$ ) accompanied with a large increase in the spin-orbit splitting energy ($\bigtri…

Global quantum correlations in finite-size spin chains

S. Campbell, L. Mazzola, G. De Chiara +4

We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently prop…
