Abstract

Itinerant ferromagnetism at room temperature is a key ingredient for spin transport and manipulation. Here, we report the realization of nearly-room-temperature itinerant ferromagnetism in Co doped Fe5GeTe2 thin flakes. The ferromagnetic transition temperature TC (323 K - 337 K) is almost unchanged when thickness is down to 12 nm and is still about 284 K at 2 nm (bilayer thickness). Theoretical calculations further indicate that the ferromagnetism persists in monolayer Fe4CoGeTe2. In addition to the robust ferromagnetism down to the ultrathin limit, Fe4CoGeTe2 exhibits an unusual temperature- and thickness-dependent intrinsic anomalous Hall effect. We propose that it could be ascribed to the dependence of band structure on thickness that changes the Berry curvature near the Fermi energy level subtly. The nearly-room-temperature ferromagnetism and tunable anomalous Hall effect in atomically thin Fe4CoGeTe2 provide opportunities to understand the exotic transport properties of two-dimensional van der Waals magnetic materials and explore their potential applications in spintronics., Comment: 28 pages, 4 figures, 1 table

36. Evolution of ultra-flat band in van der Waals kagome semiconductor Pd$_{3}$P$_{2}$(S$_{1-x}$Se$_{x}$)$_{8}$

Abstract

We investigate the evolutions of structural parameters, optical properties, and electronic structures of a van der Waals kagome semiconductor Pd$_{3}$P$_{2}$S$_{8}$ with Se doping. When the doping level of Se increases, the bandgaps of Pd$_{3}$P$_{2}$(S$_{1-x}$Se$_{x}$)$_{8}$ single crystals decrease gradually, accompanying with the expanded unit cells. The first-principles calculations show that there is a flat band (FB) near the Fermi level in bulk Pd$_{3}$P$_{2}$S$_{8}$. This FB mainly originates from the $d_{z^2}$-like orbitals of Pd atoms in the Pd kagome lattice, which have a finite interlayer electron hopping perpendicular to the PdS$_4$ square plane. The interlayer hopping can be reinforced with Se doping, inducing a stronger interlayer coupling via the chalcogen atoms at apical sites, which reduces the bandgap and enhances the cleavage energy. In contrast, the varnishing interlayer hopping in the two-dimensional limit results in the formation of ultra-FB in the monolayers of these compounds. The easy exfoliation and the existence of unique ultra-FB near $E_{\rm F}$ make Pd$_{3}$P$_{2}$(S$_{1-x}$Se$_{x}$)$_{8}$ a model system to explore the exotic physics of FB in 2D kagome lattice., Comment: 6 pages, 4 figures

47. Antisymmetric magnetoresistance due to domain wall tilting in perpendicular magnetized films

Abstract

We report the observation of the antisymmetric magnetoresistance (MR) in perpendicular magnetized CoTb films with inhomogeneous magnetization distribution driven by gradient magnetic field. By synchronously charactering the domain pattern evolution during transport measurements, we demonstrate that the nonequilibrium currents in the vicinity of tilting domain walls give rise to such anomalous MR. Moreover, theoretical calculation and analysis reveal that the geometry factor of the multidomain texture plays a dominant role in generating the nonequilibrium current. The explicitly established interplay between the anomalous transport behaviors and the particular domain wall geometry is essential to deepening understanding of the antisymmetric MR, and pave a new way for designing novel domain wall electronic devices.

Abstract

Early exposure to family material hardship is an essential risk for problematic mobile phone use (PMPU). However, less is known about the reason for the association between early material hardship and PMPU. One possibility is that early hardship is a stressor that negatively affects brain structure, increasing the risk for PMPU. In testing this model, we also took into account the possible mitigating effect of strong parent-child attachment in this risk process. Participants were 45 young adults aged 18 to 23 years old who completed questionnaires to assess early material hardship, PMPU, and parental attachment. Deficits in brain structure were measured by estimating grey matter volume (GMV) using a voxel-based morphometry method via structural magnetic resonance imaging. Results revealed a significant association between early exposure to family material hardship and decreased GMV in right ventromedial prefrontal cortex (vmPFC), left orbital inferior frontal cortex (orbIFC) and left middle cingulate cortex (MCC). Importantly, subsequent structural equation modeling showed that decreased GMV within vmPFC fully mediated the association between high family material hardship and PMPU. Furthermore, stronger parental attachment mitigated the risk of decreases in vmPFC volume on PMPU following early exposure to family material hardship., Author(s): Xiaoyu Zheng [sup.1] [sup.2] , Junchao Li [sup.3] , Mei Li [sup.4] , Zhengxinyue Wang [sup.2] , Xinyu Cao [sup.2] , Yuanyuan Chen [sup.5] , Jianjun Zhu [sup.5] Author [...]
