Journal ArticleDOI
Ferromagnetism above room temperature in bulk and transparent thin films of Mn-doped ZnO
Parmanand Sharma,Parmanand Sharma,Amita Gupta,K. V. Rao,Frank J. Owens,Renu Sharma,Rajeev Ahuja,J. M. Osorio Guillen,Börje Johansson,Börje Johansson,G. A. Gehring +10 more
TL;DR: The first observations of ferromagnetism above room temperature for dilute (<4 at%) Mn-doped ZnO semiconductors are reported, promising new spintronic devices as well as magneto-optic components.
Journal ArticleDOI
Role of titanium in hydrogen desorption in crystalline sodium alanate
TL;DR: The role of Ti in improving the thermodynamics of hydrogen desorption in crystalline sodium alanate (NaAlH4) has been investigated by using the density functional theory as discussed by the authors.
Journal ArticleDOI
Titanium metal at high pressure : Synchrotron experiments and ab initio calculations
Rajeev Ahuja,Leonid Dubrovinsky,Natalia Dubrovinskaia,J. M. Osorio Guillen,Maurizio Mattesini,Börje Johansson,Tristan Le Bihan +6 more
TL;DR: The high pressure behavior of titanium metal was investigated experimentally using angle dispersive synchrotron x-ray diffraction as well as theoretically using ab initio electronic structure methods as mentioned in this paper.
Journal ArticleDOI
Pressure-induced structural transformations in the Mott insulator FeI 2
G. Kh. Rozenberg,Moshe P. Pasternak,W. M. Xu,Leonid Dubrovinsky,J. M. Osorio Guillen,Rajeev Ahuja,B. Johansson,T. Le Bihan +7 more
TL;DR: In this article, a full-profile refinement of the layered antiferromagnetic (FeI) crystallographic structures at pressures up to 70 GPa were performed combined with ab initio calculations to particularly elucidate the structural aspects of the recently observed pressure-induced quenching of the orbital term of the Fe 2+ moment and of the Mott transition.
Journal ArticleDOI
CO Oxidation Catalytic Effects of Intrinsic Surface Defects in Rhombohedral LaMnO3.
TL;DR: In this article , the intrinsic defects of a rhombohedral perovskite-like structure of LaMnO3 and their implications on CO catalytic properties were studied.
