Among the recently discovered 2D intrinsic van der Waals (vdW) magnets, Fe3 GeTe2 (FGT) has emerged as a strong candidate for spintronics applications, due to its high Curie temperature (130 - 220 K) and magnetic tunability in response external stimuli (electrical field, light, strain). Theory predicts that magnetism of FGT can be significantly modulated by an strain. However, experimental evidence is needed validate this prediction understand underlying mechanism strain-mediated vdW system....
Although magnetic order is suppressed by a strong frustration, it appears in complex forms such as cycloid or spin density wave weakly frustrated systems. Herein, we report magnetically two-dimensional (2D) van der Waals material CrPSe3. Polycrystalline CrPSe3 was synthesized at an optimized temperature of 700 °C to avoid the formation any secondary phases (e.g., Cr2Se3). The antiferromagnetic transition appeared TN ≈ 127 K with large Curie-Weiss θCW -301 via susceptibility measurements,...
In the South Asia region, tungsten deposits are mostly distributed in China block, covering and North Vietnam. These host majority of mineralization with over 10 million tons WO3. Northeastern Vietnam contains Nui Phao W-F-Cu-Au-Bi deposit, one largest mine world. It is characterized by both skarn greisen features genetically linked to Late Cretaceous Da Lien two-mica granite from Pia Oac Complex. Furthermore, there another presumably age at this location, Thien Ke intrusion, which also a...
${\mathrm{Mn}}_{3}{\mathrm{O}}_{4}$ represents a model system for probing geometrically frustrated magnetism, and studying the magnetic behavior of material under high pressure could yield new insights into magnetostructural coupling structurally driven ordering transitions that are otherwise not observable at ambient pressure. We report here systematic study crystal structures up to 37 20 GPa using x-ray neutron powder diffraction techniques, respectively. find upon compression, structure...
Evolution of magnetic entropy change |Δ S m | as functions temperature and field for a LiSm(PO 3 ) 4 single crystal.
The stoichiometry value x of WOx , or its oxidation state, is crucial for improving performances the hole-selective contact heterojunction silicon solar cell. However, it challenging to tune films' state using well-known evaporation method. In this study, a simulation was performed analyze effect on short-circuit current (Jsc) loss, attributed in device. Compared thickness layer, has more important role minimizing Jsc loss. Based simulation, /c-Si cells having contacts with tuned vary were...
In this paper, we introduce a new phase of two-dimensional aluminum monochalcogenide, namely C 2h -AlX (X = S, Se, and Te).
Context: Virus infection is a well-known risk factor for asthma exacerbations in temperate and subtropical countries, particularly atopic children. However, the has not been well-described tropical countries including Vietnam. Aims: To compare odds of virus hospitalized children with severe versus moderate exacerbations. Settings Design: A cross-sectional study was conducted at Children’s Hospital 1, Ho Chi Minh City, Children who were admitted to hospital diagnosed or recruited study....
Group III monochalcogenide compounds can exist in different polymorphs, including the conventional D 3h and C 2h phases.
Spin-driven ferroelectricity phenomena have drawn great interest in the scientific community due to potential application spintronics and their complex physical mechanisms. A noticeable example of this is multiferroic $\mathrm{BaYFe}{\mathrm{O}}_{4}$ that exhibits an unconventional magnetoelectric (ME) coupling uncorrelated behavior ferroelectric cycloidal states under applied magnetic field. To shed more light on spin-driven ME effect, a high-quality sample was synthesized by standard...

<title>Abstract</title> This study investigates the quantities of Rare Earth Elements (REEs) and Potentially Toxic (PTEs) in Dong Nai Province's surface soils. Atomic Absorption Spectrometry (AAS) Instrumental Neutron Activation Analysis (INAA) are used to determine element concentrations. To validate concentration results, established reference materials (NIST 2711 IAEA Soil-7) were used. Element concentrations followed a certain order, with Mn, Cr, V, Zn dominating, except for Al, which...
