Strain-induced ferromagnetism in antiferromagnetic LuMnO3 thin films.
نویسندگان
چکیده
Single phase and strained LuMnO(3) thin films are discovered to display coexisting ferromagnetic and antiferromagnetic orders. A large moment ferromagnetism (≈1μ(B)), which is absent in bulk samples, is shown to display a magnetic moment distribution that is peaked at the highly strained substrate-film interface. We further show that the strain-induced ferromagnetism and the antiferromagnetic order are coupled via an exchange field, therefore demonstrating strained rare-earth manganite thin films as promising candidate systems for new multifunctional devices.

Mean-field simulation of metal oxide antiferromagnetic films and multilayers
In this work the magnetization in antiferromagnetic thin films and multilayers with interlayer exchange coupling is simulated using mean-field approximation. Transition-metal oxide antiferromagnets are modeled as multiplane magnetic systems with 1 to 11 planes and the magnetization M is calculated as a function of temperature T . The antiferromagnetic films exhibit ferromagnetism when the numbe...
متن کاملLocal weak ferromagnetism in single-crystalline ferroelectric BiFeO3.
Polarized small-angle neutron scattering studies of single-crystalline multiferroic BiFeO(3) reveal a long-wavelength spin density wave generated by ∼1° spin canting of the spins out of the rotation plane of the antiferromagnetic cycloidal order. This signifies weak ferromagnetism within mesoscopic regions of dimension 0.03 microns along [110], to several microns along [111], confirming a long-...
متن کاملStrain-induced high-temperature perovskite ferromagnetic insulator
Ferromagnetic insulators are required for many new magnetic devices, such as dissipationless quantum-spintronic devices, magnetic tunneling junctions, etc. Ferromagnetic insulators with a high Curie temperature and a high-symmetry structure are critical integration with common single-crystalline oxide films or substrates. So far, the commonly used ferromagnetic insulators mostly possess low-sym...
متن کاملFirst-principles study of ferromagnetism in epitaxial Si-Mn thin films on Si(001).
Density-functional theory calculations are employed to investigate both the epitaxial growth and the magnetic properties of thin Mn and MnSi films on Si(001). For single Mn adatoms, we find a preference for the second-layer interstitial site. While a monolayer Mn film is energetically unfavorable, a capping-Si layer significantly enhances the thermodynamic stability and induces a change from an...

Oxygen vacancies (V(O)) effects on magnetic ordering in Eu₀.₅Ba₀.₅TiO₃₋δ (EBTO₃₋δ) thin films have been investigated using a combination of experimental measurements and first-principles density-functional calculations. Two kinds of EBTO₃₋δ thin films with different oxygen deficiency have been fabricated. A nuclear resonance backscattering spectrometry technique has been used to quantitatively ...
