Spin glasses (SGs) arise from the frustration of competing magnetic interactions without long-range order; hence they tend to be destabilized by thermal fluctuation and exhibit a rather low glass transition temperature, presenting major challenge for SG research applications. Here, we report an unusual state in quaternary Fe-Co-Ni-Mn chemically complex alloys (CCAs). The exhibits ultrahigh freezing temperature above room well exceeding that conventional bulk SGs, as unique fast relaxation...
While there has been significant pursuits and interest in single element metallic glass (MG), it extremely difficult to obtain. Despite the recent advances preparing MGs, massive production of stable monatomic MGs is great challenge. Here, we show that Ta MG, presenting identical structural characteristics those from liquid quenching, can be produced using conventional ion beam deposition on a room temperature substrate. The amorphous structure retained even after being annealed at 573 K for...
We report the electron dynamics of recently discovered quasi-one-dimensional Kondo lattice compound ${\mathrm{CeCo}}_{2}{\mathrm{Ga}}_{8}$ by optical spectra measurements using polarized light. For an electric field along $c$ axis, high-temperature Drude-like peak is found to split into two distinct components below coherence temperature ${T}^{*}$, including a narrower at low frequencies characterizing emergent heavy state with large mass enhancement, and midinfrared Lorentz-like originating...
Abstract:
The origin of anomalous Hall effect (AHE) in ferromagnetic metallic glasses (MGs) is not yet understood completely. Here, the AHE explored Fe78Si9B13 MGs. We find behavior resistivity at low temperature seems to be more likely due structure rather than Kondo-type effect. More importantly, we firstly primitive experiment conductivity ({\sigma}AH) without separation extrinsic contribution has a linear magnetization (Mz) dependence when changing, which another feature intrinsic mechanism and...
Topologically protected spin textures, such as skyrmions1,2 and vortices3,4, are robust against perturbations, serving the building blocks for a range of topological devices5-9. In order to implement these devices, it is necessary find ultra-small textures at room temperature, because small size implies higher charge density, stronger signal transport10,11 memory density or integration quantum However, finding high temperatures still great challenge up now. Here we in Fe78Si9B13 amorphous...
