Valence-free open nanoparticle superlattices
Binay P. Nayak, Zinnia Mallick, Wenjie Wang +7
A cornerstone of advanced materials design is establishing a framework for assembling nanoparticle superstructures with tailored symmetries. A longstanding challenge has been assem…
Tunneling magnetoresistance in magnetic tunnel junctions with a single ferromagnetic electrode
Kartik Samanta, Yuan-Yuan Jiang, Tula R. Paudel +2
Magnetic tunnel junctions (MTJs) are key components of spintronic devices, such as magnetic random-access memories. Normally, MTJs consist of two ferromagnetic (FM) electrodes sepa…
In-plane quasi-single-domain BaTiO via interfacial symmetry engineering
J. W. Lee, K. Eom, T. R. Paudel +18
The control of the in-plane domain evolution in ferroelectric thin films is not only critical to understanding ferroelectric phenomena but also to enabling functional device fabric…
Computational Optimization of MnBi to Enhance Energy Product
Tula R Paudel, Bhubnesh Lama, Parashu Kharel
High energy density magnets are preferred over induction magnets for many applications, including electric motors used in flying rovers, electric vehicles, and wind turbines. Howev…
Coexistence of phases and interphase boundaries in BaTiO3
T. A. Liebsch, V. L. Sobolev
A theoretical analysis of the internal structure of interphase boundaries separating domains of coexisting phases are presented for the perovskite ferroelectric BaTiO3. The tempera…
Growth, electrical, structural, and magnetic properties of half-Heusler CoTiFeSb
Sean D. Harrington, Anthony D. Rice, Tobias Brown-Heft +11
Epitaxial thin films of the substitutionally alloyed half-Heusler series CoTiFeSb were grown by molecular beam epitaxy on InAlAs/InP(001) substrates for concentrations…
Relative Cooling Power Enhancement by Tuning Magneto-structural Stability in Ni-Mn-In Heusler Alloys
Jing-Han Chen, Nickolaus M. Bruno, Zhenhua Ning +5
Off-stoichiometric NiMnIn Heusler alloys have drawn recent attention due to their large magnetocaloric entropy change associated with the first-order magneto-structural transit…
Multiband Electronic Structure of Magnetic Quantum Dots: Numerical Studies
D. Rederth, R. Oszwaldowski, A. G. Petukhov +1
Semiconductor quantum dots (QDs) doped with magnetic impurities have been a focus of continuous research for a couple of decades. A significant effort has been devoted to studies o…
Fermi level position, Coulomb gap, and Dresselhaus splitting in (Ga,Mn)As
S. Souma, L. Chen, R. Oszwaldowski +5
Carrier-induced nature of ferromagnetism in a ferromagnetic semiconductor, (Ga,Mn)As, offers a great opportunity to observe novel spin-related phenomena as well as to demonstrate n…
Zr and Sn substituted (NaBi)TiO based solid solutions
V. M. Ishchuk, L. G. Gusakova, N. G. Kisel +3
Formation of phases during the solid state synthesis of the barium-modified NBT solid solutions, with substitutions of zirconium and tin ions for titanium are investigated. The syn…
Ferromagnetism and spin polarized charge carriers in InO thin films
Raghava P. Panguluri, P. Kharel, C. Sudakar +6
We present evidence for spin polarized charge carriers in InO films. Both InO and Cr doped InO films exhibit room temperature ferromagnetism after vacuum an…
Metal-insulator transition and giant anisotropic magnetoresistance in ultra thin (Ga,Mn)As
R. R. Gareev, A. Petukhov, M. Schlapps +4
MBE-grown, 5 nm-thick annealed Ga0.95Mn0.05As films with Tc~90K demonstrate transition from metallic to insulating state below To~10K, where sheet resistances Rsh~h/e2 and both lon…
Thermodynamics of carrier-mediated magnetism in semiconductors
A. G. Petukhov, Igor Zutic, Steven C. Erwin
We propose a model of carrier-mediated ferromagnetism in semiconductors that accounts for the temperature dependence of the carriers. The model permits analysis of the thermodynami…
Variable-Range Hopping of Spin Polarons: Magnetoresistance in a Modified Mott Regime
M. Foygel, R. D. Morris, A. G. Petukhov
We analize electrical conductivity controlled by hopping of bound spin polarons in disordered solids with wide distributions of electron energies and polaron shifts (barriers). By…
Electron Spin Polarization in Resonant Interband Tunneling Devices
A. G. Petukhov, D. O. Demchenko, A. N. Chantis
We study spin-dependent interband resonant tunneling in double-barrier InAs/AlSb/ GaMnSb heterostructures. We demonstrate that these structures can be used as spin filters utilizin…
