Crystals with full tetrahedral symmetry may exhibit antichiral ferromagnetic ordering. This spontaneous modulation of the magnetization direction is characterized by a spatial alternation between right and left handedness. In addition to unconventional ground state, revealed ordering gives rise rich phenomena, such as unique magnetic domains skyrmions.

Submitted for the MAR09 Meeting of The American Physical Society Development of ferromagnetism in Pd nanoparticles with reduction in size MOHINDAR SEEHRA, JAMES RALL, West Virginia University, J. LIU, C. ROBERTS, Auburn University — Bulk fcc Pd is a paramagnet just missing the Stoner criterion for ferromagnetism (N(EF )I > 1) [1]. Several groups have reported weak ferromagnetism in 2-4 nm Pd na...

Two-dimensional nanostructures with controllable magnetic and electronic properties are desirable for their versatile applications in quantum devices. Here, we present a first-principles design on their magnetic and electronic switching controlled by tension. We find that hydrogenated VTe2 monolayer experiences a transfer from anti-ferromagnetism to ferromagnetism via a turning-point of paramag...

New surprises continue to be revealed about La$_2$CuO$_4$, the parent compound of original cuprate superconductor. Here we present neutron scattering evidence that structural symmetry is lower than commonly assumed. The static distortion results in anisotropic Cu-O bonds within CuO$_2$ planes; such anisotropy relevant pinning charge stripes hole-doped samples. Associated with extra modulation a...

Emergent phenomena at complex-oxide interfaces have become a vibrant field of study in the past two decades due to rich physics and wide range possibilities for creating new states matter novel functionalities potential devices. The electronic-structural characterization such presents unique challenge lack direct yet nondestructive techniques probing buried layers with required Ångstrom-level r...

Ferromagnetism and its evolution in the orthorhombic perovskite system Sr(1-x)Ca(x)RuO3 have been widely believed to correlate with structural distortion. The recent development of high-pressure synthesis of the Ba-substituted Sr(1-y)Ba(y)RuO3 makes it possible to study ferromagnetism over a broader phase diagram, which includes the orthorhombic Imma and the cubic phases. However, the chemical ...

Introduction / Background: MR imaging of arthroplasty has traditionally been limited by the presence of artifact generated by the metallic components, which comparatively demonstrate higher magnetic susceptibility than the adjacent bone and soft tissue (1-3). The sources of these artifacts include induction of radiofrequency eddy currents in the metal, warping of the slice during slice selectio...

Ferromagnetism was observed in a Pt(100) ultrathin film deposited on SrTiO3(100) substrate. The ferromagnetism, which appears films with thicknesses of 2.2–4.4 nm, periodically changes period approximately 1 nm (5–6 monolayers) depending the thickness. This is consistent derived from quantum-well states formed thin film. X-ray magnetic circular dichroism measurements show evidence appearance in...
