Design of magnetic spirals in layered perovskites: extending the stability range far beyond room temperature [PDF]
In insulating materials with ordered magnetic spiral phases, ferroelectricity can emerge due to the breaking of inversion symmetry. This property is of both fundamental and practical interest, in particular with a view to exploiting it in low-power ...

Synthesis and Characterization of Novel V‐Type Hexaferrite BaFe9−xSnxO15
GA: The crystal structure of a new quaternary V‐type hexaferrite with the composition BaFe9−xSnxO15, found in the system Ba–Fe–Sn–O, is reported. A novel V‐type hexaferrite with the composition BaFe9−xSnxO15 with 1.57 ≤ x ≤ 1.84 (from wavelength dispersive X‐ray spectroscopy [WDX] data) is synthesized by reacting BaCO3, Fe2O3, SnO2, and Na2CO3 as flux ...

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

ABSTRACT The integration of hard magnetic barium hexaferrite (BHF) nanoplatelets into a dense poly(ethylene succinate) (PES) polyester matrix produces an exciting biodegradable thermoplastic magnetic polymer nanocomposite. In this work, scandium‐substituted BHF nanoplatelets are grown and stabilized in hexadecyltrimethylammonium bromide (CTAB ...

Triple‐Stimuli Responsive Soft Robots with Photo‐Programmable Ferriferous Oxide Particle Patterns
The in situ generation of Fe3O4 nanoparticles in polymer substrate is realized by combining photo‐reduction of Fe3+ to Fe2+ and hydrolytic reaction of the two ions. By spatiotemporal control of UV light irradiation, the distribution of Fe3O4 nanoparticle can be well controlled, which enables the composite with magnetic field, NIR light, and moisture ...

Circulator based on spoof surface plasmon polaritons
Circulators based on spoof surface plasmon polaritons are designed and analyzed. In the letter, we use blade structure to realize the propagation of SSPPs wave and a matching transition is used to feed energy from coplanar waveguide to the SSPPs. And the
