Jan 31, 2018 Hematite has unpaired electrons that cause its magnetic properties. It is paramagnetic because it has only ferric ion (Fe 3).The electron configuration of Fe 3 is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present. Therefore, hematite can be separated from a mixture using high-intensity magnetic separation methods which use magnetic fields with intensity ranging from 0.02-4 ... Jul 03, 2019 As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. -iron, cobalt, and nickel are ferromagnetic, while -iron, manganese, and chromium are antiferromagnetic. Lithium gas is magnetic when cooled below 1 kelvin. Magnetic anisotropy means that the magnetic properties depend on the direction in which they are measured. It strongly affects the shape of the M-H curve. Key phenomenon used in the design of most commercial magnetic materials. Kinds of anisotropy a) Crystal anisotropy (magnetocrystalline anisotropy) b) Shape anisotropy c) Stress anisotropy

The superhydrophobic magnetic sponge were prepared by Fe3O4 nanoparticals and stearic acid which were coated on the surface of polyurethane sponge. PU sponge was immersed in a solution of HDPE/magnetic (Fe 3 O 4) particles and then heated to 140C, close to the melting point of HDPE. The HDPE, at this temperature, allowed wrapping the Fe 3 O 4 particles onto the backbone of the PU sponge, resulting in a magnetic/hydrophobic sponge. Further modification of the magnetic/hydrophobic Aerosol pyrolysis of Fe(CO) 5 in an atmosphere of sulfur vapor under a magnetic field is shown to controllably produce iron pyrite (FeS 2) three-dimensional nanochain networks.The formation processes of the FeS 2 nanochain networks are systematically studied (1) thermal decomposition of Fe(CO) 5 followed by Fe nanoparticle assembly into one-dimensional chains and then three-dimensional ...

In this paper, we manufacture a magnetic sponge via a simple method through dipping melamine sponge in Fe 3 O 4 magnetic nano-particles, 3-hydroxytyramine hydrochloride and 1- dodecanethiol under ultrasonication, and then hydrophobicity modified with OTS. Apr 24, 2020 Importantly, the PDMSVMTFe 3 O 4 dPU sponge instantly adsorbed oil floating on water under magnetic field driving. Furthermore, PDMSVMTFe 3 O 4 dPU sponge absorbed various oils and chemical with ideal selectivity, absorption capacity (up to 40 times of its own weight), speed, and recyclability (exceeding 100 cycles). These magnetic pertubations are called induced fields. Induced fields would require large global-scale conducting paths near the surface. For icy moons, the most likely agent of this is salty subsurface oceans. Unfortunately, finding these magnetic fields is not as simple a task as first percieved. Europa is a moon of Jupiter, the most hostile ...

Mumetal high permeability magnetic shielding is a soft ferromagnetic material that does not retain a macroscopic internal field after the removal of an external magnetizing field. Mu metal is a non-oriented 80% nickel-iron-molybdenum alloy. The OHM sponge is synthesized by coating a polyurethane sponge (soft) with a nanocomposite, made of mixed metal oxide nanoparticles, such as Fe 3O 4, and graphite (hard). We have demonstrated exceptional macroscale oleophilicity and hydrophobicity both in oil remediation tests and in isolated, controlled contact angle tests.

The higher magnification (5000 times) SEM images show that the smooth skeleton surface of pristine sponge became rough after Fe 3 O 4 particles deposited on the MS substrate (Fig. 6b) and the WCA of Fe 3 O 4 /MS achieved 135 , which demonstrated the existence of Fe 3 O 4 on MS and it would be further confirmed by the following XRD and XPS tests. Jun 29, 2021 However, the unambiguous identification of the magnetic textures inherent to vdW magnets, for example, whether the magnetic twists (skyrmions/domain walls) are Nel- or Bloch-type, is unclear. Here we demonstrate that the magnetic twists can be tuned between Nel and Bloch-type in the vdW magnet Fe 3 GeTe 2 (FGT) with/without interfacial DMI. Aug 24, 2011 The magnetic behaviors in Fe(Se,Te) systems have been investigated systematically using density functional calculations. At the experimental lattice parameters, the ground state is found to be in the double stripe magnetic phase for FeTe but in the single stripe magnetic phase for FeSe and FeSe 0. 5 Te 0. 5, and there is no preference in the different easy axes of magnetization.

Jun 01, 2009 Most dilute magnetic semiconductors exist either in ferromagnetic (e.g., GaAsMn) or antiferromagnetic (ZnSeMn) phases at low temperature. This alignment persists even after carriers are introduced, although the preference may change as a function of doping. Using first-principles calculations, we found that the stable magnetic phase of GaNFe is ferrimagnetic under hole doping, Aug 19, 2021 Fe-doped III-V ferromagnetic semiconductors (FMSs) such as (In,Fe)As, (Ga,Fe)Sb, (In,Fe)Sb, and (Al,Fe)Sb are promising materials for spintronic device applications because of the availability of both n- and p-type materials and the high Curie temperatures.
