Journal ArticleDOI
High temperature ferromagnetism with a giant magnetic moment in transparent co-doped SnO(2-delta).
S. B. Ogale,R. J. Choudhary,James P. Buban,Samuel E. Lofland,S. R. Shinde,Sangeeta Kale,V. N. Kulkarni,Joshua Higgins,C. Lanci,Jeffrey R. Simpson,Nigel D. Browning,S. Das Sarma,H. D. Drew,R. L. Greene,T. Venkatesan +14 more
TL;DR: The occurrence of room temperature ferromagnetism is demonstrated in pulsed laser deposited thin films of Sn(1-x)Co(x)O(2-delta) (x<0.3) and a giant magnetic moment of 7.5+/-0.5 micro(B)/Co, not yet reported in any diluted magnetic semiconductor system.
Journal ArticleDOI
Strong surface scattering in ultrahigh mobility Bi2Se3 topological insulator crystals
Nicholas P. Butch,Kevin Kirshenbaum,P. Syers,Andrei B. Sushkov,Gregory S. Jenkins,H. D. Drew,Johnpierre Paglione +6 more
TL;DR: A comprehensive analysis of Shubnikov de Haas oscillations, Hall et al. as discussed by the authors showed that the measured electrical transport can be attributed solely to bulk states, even at 50 mK at low Landau level filling factor, and in the quantum limit.
Journal ArticleDOI
Effect of hydrogen on pb(zr, ti)o3-based ferroelectric capacitors
Sanjeev Aggarwal,S. R. Perusse,C. W. Tipton,R. Ramesh,H. D. Drew,T. Venkatesan,D. B. Romero,V. B. Podobedov,A. Weber +8 more
TL;DR: In this article, it was shown that hydrogen incorporation is the primary mechanism for the degradation of ferroelectric properties and the most probable site for hydrogen ions is discussed based on ionic radii, crystal structure, electrical properties, and Raman spectra.
Journal ArticleDOI
Electromagnons in multiferroic YMn2O5 and TbMn2O5.
TL;DR: Electromagnons are found to be directly responsible for the steplike anomaly of the static dielectric constant at the commensurate--incommensurate magnetic transition and are the origin of the colossal magneto-dielectric effect reported in these multiferroics.
Journal ArticleDOI
Origin of electromagnon excitations in multiferroic RMnO3.
R. Valdés Aguilar,Maxim Mostovoy,Andrei B. Sushkov,Chenglin Zhang,Young Jai Choi,Sang-Wook Cheong,H. D. Drew +6 more
TL;DR: A model incorporating the structural characteristics of this family of manganites that is confirmed by far infrared transmission data as a function of temperature and magnetic field and inelastic neutron scattering results is presented.
