Influence of Ion Beam Irradiation on Optical and Magnetic Properties of Transparent Mn Doped ZnO Thin Films, Suitable for Sensor Applications
TL;DR: In this article , the authors describe modification in physical properties of Zn0.95Mn 0.05O films by ion beam irradiation and show that magnetism is strongly correlated with intrinsic defects present in these films.

Bulk Rashba spin splitting and Dirac surface state in $p$-type (Bi$_{0.9}$Sb$_{0.1})_2$Se$_3$ single crystal.
P. K. Ghose,Sudipta Bandyopadhyay,T. K. Dalui,J.-C. Tseng,J. K. Dey,R. Tomar,S. Chakraverty,Subham Majumdar,Indra Dasgupta,Saurav Giri +9 more
TL;DR: In this article, the authors show that the origin of the bulk Rashba spin splitting (RSS) is due to a structural transition to a non-centrosymmetric $R3m$ phase below $\sim$ 30 K. The existence of both the bulk RSS and Dirac surface states are confirmed by density functional theory calculations.
