Abstract Cobalt oxyhydroxide (CoOOH) is a promising catalytic material for oxygen evolution reaction (OER). In the traditional CoOOH structure, Co 3+ exhibits low-spin state configuration ( $${t}_{2{{{{{\rm{g}}}}}}}^{6}{e}_{{{{{{\rm{g}}}}}}}^{0}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mrow> <mml:mi>t</mml:mi> </mml:mrow> <mml:mn>2</mml:mn> <mml:mi>g</mml:mi> <mml:mn>6</mml:mn> </mml:msubsup> <mml:mi>e</mml:mi> <mml:mn>0</mml:mn> </mml:math> ), with...

Abstract The electrical control of the non-trivial topology in Weyl antiferromagnets is great interest for development next-generation spintronic devices. Recent studies suggest that spin Hall effect can switch topological antiferromagnetic order. However, switching efficiency remains relatively low. Here, we demonstrate effective manipulation order semimetal Mn 3 Sn using orbital torques originating from either metal or oxide CuO x . Although convert current to on its own, find inserting a...

Abstract Chiral multiferroics offer remarkable capabilities for controlling quantum devices at multiple levels. However, these materials are rare due to the competing requirements of long-range orders and strict symmetry constraints. In this study, we present experimental evidence that coexistence ferroelectric, magnetic orders, crystallographic chirality is achievable in hybrid organic-inorganic perovskites [( R / S )- β -methylphenethylamine] 2 CuCl 4 . By employing Landau mode analysis,...

Sleep problems and cancer-related fatigue are common symptoms in women for breast cancer, during after treatment. Identifying key intervention targets this symptom cluster may improve patient reported outcomes. This study aimed to explore the relationship between sleep identify optimal targets. In "Be Resilient Breast Cancer" program, self report data were collected on Multidimensional Fatigue Symptom Inventory-Short Form Pittsburgh Quality Index. Gaussian network analysis was employed...

In order to advance the silicon integrated circuit technology, researchers have been searching for memory and logic devices with new physical state variables other than charge. Spin device that adds one degree of freedom-electron spin charge has considered as a promising candidate due its low power consumption, built-in memory, high scalability. Here, we demonstrate variable – current direction on sample can be introduced into operation. The is vector. For various input currents along...

The pursuit of robust, long-range magnetic ordering in two-dimensional (2D) materials holds immense promise for driving technological advances. However, achieving this goal remains a grand challenge due to enhanced quantum and thermal fluctuations as well chemical instability the 2D limit. While has been realized atomically thin flakes transition metal chalcogenides halides, these often suffer from air instability. In contrast, carbon-based are stable enough, yet lies creating high density...

As a typical nonlinear magnetoresistance, unidirectional magnetoresistance (UMR) has recently been observed in antiferromagnetic (AFM) systems with canted spin structure. However, profound understanding of AFM UMR induced by interfacial spin-orbit coupling (SOC) is still lacking to date. In this paper, we choose van der Waals $\mathrm{CrP}{\mathrm{S}}_{4}$ due the relatively low magnetic anisotropy and weak interlayer coupling, which enables canted-AFM state between two adjacent layers under...
