“…In turn, the occurrence of PMA together with the interfacial Dzyaloshinskii-Moriya interaction (iDMI) in multilayers can give rise to promising chiral structures such as magnetic bubbles or skyrmions 7–9 . Recently, it has been demonstrated that magnetic bubbles in a PMA multilayer can be imprinted into an adjacent soft magnetic layer with in-plane anisotropy, leading to strong modifications of the high frequency magnetization dynamics of the structure 10 . In sum, magnetic interactions and anisotropies present a relationship with the formation processes of the magnetic domains and domain walls and are strongly influenced by the interfaces in heterostructure thin films.…”

With the continuing interest in new magnetic materials for sensor devices and data storage applications, the community needs reliable and sensitive tools for the characterization of such materials. Soft X-rays tuned to elemental absorption edges are a depth and element sensitive probe of magnetic structure at the nanoscale, and scattering measurements have the potential to provide 3D magnetic structural information of the material. In this work we develop a methodology in transmission geometry that allows one to probe the spatial distribution of the magnetization along the different layers of magnetic heterostructures. We study the in-plane/out-of-plane transition of magnetic domains in multilayer thin film systems consisting of two layers of NiFe top and bottom, and a 50 repeat Co/Pd multilayer in the centre. The experimental data are analysed by simulating scattering data starting from micromagnetic simulations, and we find that the out of plane domains of the Co/Pd multilayer intrude into the NiFe layers to a greater extent than would be expected from micromagnetic simulations performed using the standard magnetically isotropic input parameters for the NiFe layers.

“…To better elucidate the effect of out‐of‐plane coupling, MD simulations were performed on graphene using the Projector‐augmented‐wave Perdew–Burke–Ernzerhof‐Graphene (PPBE‐G) model [ 39,40 ] with and without a model substrate. The PPBE‐G model was developed by force‐matching density function theory with the PBE exchange correlation functional, with projector‐augmented‐wave pseudo‐potential for core electrons.…”

2D materials have generated enormous interest because of its unique physical properties and promising applications. 2D materials such as graphene, h-BN, silicene, h-MoS 2 , and black phosphorus are expected to play a central role in nextgeneration electronic and optoelectronic devices. [1-3] The The thermal expansion coefficient (TEC) of a 2D material is a fundamental parameter for both material property and applications. A joint study is hereby reported, using Raman microspectroscopy and molecular dynamics (MD) simulations, of the substrate effects on thermal properties of graphene. It is found that besides the lateral strain induced by the substrate, out-of-plane coupling strongly affects the temperature-dependent vibrational modes and TEC of graphene. MD simulation shows significant reduction of the density of states for longer wavelength out-of-plane vibrations when the graphene is supported on an alkane substrate. The negative TEC of freestanding graphene becomes smaller when out-of-plane rippling is suppressed. In order to measure TEC of 2D materials with the out-of-plane coupling being taken into consideration, a Raman microspectroscopic scheme to separate the contributions of lateral strain and out-of-plane coupling to TEC is developed. The TEC of graphene on octadecyltrichlorosilane substrate is found to be (−0.6 ± 0.5) × 10 −6 K −1 at room temperature, which is fundamentally smaller than that of freestanding graphene. These results shed light on the fundamental understanding of the interaction between 2D material and substrate, and offer a general recipe for studying separately in-plane and out-of-plane couplings on supported materials.

“…This random domain structure is easy to induce self‐rotating waves or spin textures (such as magnetic bubbles and skyrmions), because magnetic vortices were only usually observed in spatially confined nanostructures with a high symmetry, which is beneficial to the development of high‐density magnetic storage devices.

Novel magnetic domain structures attract much attention due to their potential applications in the high performance of spintronic devices. Herein, the magnetic domains of La0.67Sr0.33MnO3 (LSMO) thin films, which epitaxially grown on (100)‐, (110)‐, and (111)‐oriented (LaAlO3)0.3(Sr2AlTaO6)0.7 (LSAT) substrates, are systematically investigated. The (100)‐ and (110)‐LSMO films show a stripe domain pattern. After in‐plane magnetic field saturation, the direction of the stripe domains in (100)‐LSMO no longer rotates with the change of magnetic field, while the stripe domains in (110)‐LSMO rotate continuously. The (111)‐LSMO films produce randomly distributed bubble‐like magnetic domains, which gradually connect into strips with the increase of the external magnetic field, and the stability of the magnetic domain in (111)‐LSMO is better than the ones in (100)‐ and (110)‐LSMO under a magnetic field. In addition, it is found that with the increase of thickness, the random domains in (111)‐LSMO films are gradually transformed into mazy domains. These phenomena can be understood by the regulable strain anisotropy and the magnetic anisotropy. Herein, an effective way is suggested to modify the magnetization anisotropy and magnetic domain because spin polarization depends strongly on the crystal surface orientation as well as epitaxial strain.
