Ferroelectricity and strain effects in orthorhombic YMnO3 thin films
J. Fontcuberta, I. Fina, L. Fàbrega +3
We report on the dielectric properties of epitaxial [001] and [100]-textured thin films of antiferromagnetic orthorhombic YMnO3 and their variation under compressive epitaxial stra…
Skin layer of BiFeO3 single crystals
X. Marti, P. Ferrer, J. Herrero-Albillos +5
A surface layer ("skin") that is functionally and structurally different from the bulk was found in single crystals of BiFeO3. Impedance analysis indicates that a previously report…
Pressure dependence of Curie temperature and resistivity in complex Heusler alloys
S. K. Bose, J. Kudrnovsky, V. Drchal +1
Using first-principles electronic structure calculations, we have studied the dependence of the Curie temperature on external hydrostatic pressure for random Ni2MnSn Heusler alloys…
Surface morphology and magnetic anisotropy in (Ga,Mn)As
S. Piano, X. Marti, A. W. Rushforth +6
Atomic Force Microscopy and Grazing incidence X-ray diffraction measurements have revealed the presence of ripples aligned along the direction on the surface of (Ga,M…
Molecular Beam Epitaxy of LiMnAs
V. Novak, M. Cukr, Z. Soban +5
We report on the molecular beam epitaxy (MBE) growth of high crystalline quality LiMnAs. The introduction of a group-I alkali metal element Li with flux comparable to fluxes of Mn…
Magnetism of mixed quaternary Heusler alloys: (Ni,T)MnSn (T=Cu,Pd) as a case study
S. K. Bose, J. Kudrnovský, V. Drchal +1
The electronic properties, exchange interactions, finite-temperature magnetism, and transport properties of random quaternary Heusler NiMnSn alloys doped with Cu- and Pd-atom…
Systematic study of Mn-doping trends in optical properties of (Ga,Mn)As
T. Jungwirth, P. Horodyska, N. Tesarova +13
We report on a systematic study of optical properties of (Ga,Mn)As epilayers spanning the wide range of accessible substitutional Mn_Ga dopings. The growth and post-growth annealin…
Strain control of magnetic anisotropy in (Ga,Mn)As microbars
C. King, J. Zemen, K. Olejník +8
We present an experimental and theoretical study of magnetocrystalline anisotropies in arrays of bars patterned lithographically into (Ga,Mn)As epilayers grown under compressive la…
First-principles design and subsequent synthesis of a material to search for the permanent electric dipole moment of the electron
K. Z. Rushchanskii, S. Kamba, V. Goian +11
We describe the first-principles design and subsequent synthesis of a new material with the specific functionalities required for a solid-state-based search for the permanent elect…
Exciton spin dynamics in spherical CdS quantum dots
P. Horodyska, P. Nemec, D. Sprinzl +3
Exciton spin dynamics in quasi-spherical CdS quantum dots is studied in detail experimentally and theoretically. Exciton states are calculated using the 6-band k.p Hamiltonian. It…
Systematic investigation of influence of n-type doping on electron spin dephasing in CdTe
D. Sprinzl, P. Horodyska, E. Belas +3
We used time-resolved Kerr rotation technique to study the electron spin coherence in a comprehensive set of bulk CdTe samples with various concentrations of electrons that were su…
