In situ electrical control of the Dzyaloshinskii-Moriya interaction (DMI) is one central but challenging goals toward skyrmion-based device applications. An atomic design defective interfaces in spin-orbit-coupled transition-metal oxides can be an appealing strategy to achieve this goal. work, by utilizing distinct formation energies and diffusion barriers oxygen vacancies at SrRuO3 /SrTiO3 (001), a sharp interface constructed between oxygen-deficient stoichiometric .

Abstract Soil erodibility, as an intrinsic soil property, reflects the susceptibility of soils to water erosion. Based on sub‐processes erosion, erodibility can be divided into dispersibility and scourability, which are caused by rainfall runoff, respectively. Both processes strongly associated with moisture. However, few studies have investigated effect antecedent moisture content erodibility. In this study, a splash test was conducted under four different conditions (dry, semi‐dry,...
Raspberry-like hollow carbon spheres have been successfully obtained by the extension of Stöber's method. The raspberry-like demonstrate a much better performance than with smooth surface in matrix-free peptide detection due to their high capability capture small molecule.
Strongly correlated perovskite oxides exhibit a plethera of intriguing phenomena and stimulate great potential for multifunctional device applications. Utilizing tunable uniaxial strain, rather than biaxial or anisotropic delivered from the crystallography single crystal substrate to modify ground state strongly has rarely been addressed phase-space control. Here, we show that physical properties La2/3Ca1/3MnO3 (LCMO) films are remarkably different depending on crystallographic orientations...

In this work, we present structured dendritic mesoporous silica@resorcinol-formaldehyde (DMS@RF) nanoparticles can be prepared through a simple one-pot colloidal method. The DMS@RF nanoparticle shows bonsai-like morphology which consists silica part spherical RF part. After systematic study on...
(K,Na)NbO3-based lead-free ferroelectric materials are highly desired in modern electronic applications and have long been considered as a strong candidate for replacing (Pb,Zr)TiO3, but most of them deficient large remnant polarization decent thermal stability.

Abstract Manipulating magnetic anisotropy in complex oxide heterostructures has attracted much attention. Here, three interface‐engineering approaches are applied to address two general issues with controlling the La 2/3 Sr 1/3 MnO 3 heterostructure. One is paradox arising from competition between Mn 3d –O 2p orbital hybridization and 6 crystal field. The other interfacial region where nonuniform MnO bond length d MnOMn angle θ disturb structural modulation. When suppressed...
We investigate the critical temperature Tc of a thin s-wave superconductor (Nb) proximity coupled to helical rare earth ferromagnet (Ho). As function Ho layer thickness, we observe multiple oscillations superimposed on slow decay, that attribute influence Nb effect. Because inhomogeneous magnetization, singlet and triplet pair correlations are present in bilayers. take both into consideration when solving self consistent Bogoliubov-de Gennes equations, reasonable agreement. also non-trivial...
