Magnetic structure and ordering of multiferroic hexagonal LuFeO_{3}.
We report on the magnetic structure and ordering of hexagonal LuFeO_{3} films of variable thickness grown by molecular-beam epitaxy on YSZ (111) and Al_{2}O_{3} (0001) substrates. These crystalline films exhibit long-range structural uniformity dominated by the polar P6_{3}cm phase, which is responsible for the paraelectric to ferroelectric transition that occurs above 1000 K. Using bulk magnet...
متن کاملDirect observation of strain-induced change in surface electronic structure.
We have observed a novel modification of a surface state due to a local strain field induced by a nanopattern formation. N adsorption on the Cu(100) surface induces a nanoscale grid pattern, where the clean Cu regions remain periodically. The lattice is contracted on the clean region by adjacent c(2 x 2)N domains, which have a larger lattice constant. On this patterned surface, we have investig...
متن کاملDirect Observation of Multiferroic Vortex Domains in YMnO3
Topological vortices with swirling ferroelectric, magnetic and structural anti-phase relationship in hexagonal RMnO3 (R = Ho to Lu, Y, and Sc) have attracted much attention because of their intriguing behaviors. Herein, we report the structure of multiferroic vortex domains in YMnO3 at atomic scale using state-of-the-art aberration-corrected scanning transmission electron microscopy (STEM). Two...

متن کاملCritical Exponents of Multiferroic Hexagonal RMnO3
A microscopic model and a Green’s function technique are developed to study the critical behavior of some multiferroics such as hexagonal RMnO3. The temperature dependence and the external field dependence of the order parameter for the magnetization are determined. The critical exponents β and δ are calculated. Applying the scaling laws γ, α and ν are also obtained. The critical exponents are ...
