Magnetization switching in nanoscale devices induced by electric currents has been a subject of intensive research in recent years.1 One of the most studied approaches is the transfer of spin angular momentum between non-collinear ferromagnetic layers, an e ect known as spin transfer torque (STT).2,3 In this case, the charge cur-
metal alloys (FeCr, FeMn, FeCo and FeNi) are study in the ferromagneticcase. We ˘nd soft-magnetic propertiesfor FeCr, FeMn while for FeCo and FeNi hard-magneticare predicted. In particular,for the family of FeNi, a candidate structure with energylower than the tetrataenite was found.The structure has a saturation magnetization(Ms) of 1.2 MA m−1,

Methods of research A formula introduced in [11, 12] was used that describes the changes in the magnetization М(Н m, Н) on the minor loops of the magnetic hysteresis of steels with respect to the maximum magnetic field intensity Н m of the partial hysteresis loop acting on the material in the magnetic field H, and Н сs, М rs and М
On the given site, which is composed of large areas of dry sand, the granulometric class ranges from fine to very coarse sand (size of grains between 0.125 and 2 mm).It appeared that the factor F, representing the intensity at the nadir, remained independent of the granulometry of the sediment (Figure 6.23).The variation of the m roughness factor is low and remains included in the interval of ...

Nov 23, 2016 The key characteristic of single-molecule magnets (SMMs) is the anisotropy-induced blocking barrier, which should be as efficient as possible, i.e., to be able to provide long magnetic relaxation times at elevated temperatures. The strategy for the design of efficient SMMs on the basis of transition-metal complexes such as Mn12Ac is well established, which is not the case of complexes ...
netic field. It was predicted by Slonczewski1 and Berger2 that magnetization of a nanomagnet may be flipped by a spin polarized current through the so-called “spin-torque” effect and this was later demonstrated experimentally.3,4 However, the early spin-torque systems were metal based that allowed only a small change in the magnetoresistance.

For example, a 1 diameter Grade 35 Neodymium Disc Magnet that is 1/4 long, will measure approximately 2,500 Gauss 1/16 away from the surface, and 2,200 Gauss 1/8 away from the surface. Can I make a magnet that I already have any stronger? Once a magnet is fully magnetized, it cannot be made any stronger - it is saturated .
The extraction of copper was quantitative in 2-stages using 1.5% (v/v) LIX 984N-C at A: O ratio of 1:2 and pH e 1.85. The CCS condition (two stages, phase ratio A:O = 1:4) obtained from the stripping isotherm study, further attributes to the enrichment (4 folds) of copper concentration in the strip solution.
The gypsum board dryer is equipped with two electromagnetic clutches. One is for gypsum boards with length between 1.8 and 2.7m, and the other for boards between 3 and 3.6m. The same as the in-feed section, the low speed and high speed sections are driven independently, and are connected via overrunning clutches

In this table the remanent flux density is the retained magnetic field B, and the SI unit for B is the Tesla (T). 1 Tesla = 10,000 gauss. The coercive force is the applied reverse magnetic field strength H required to force the net magnetic field back to zero after magnetization. The SI unit for H is A/m, and 1 A/m = 0.01257 oersteds.

Here, we show that strain induces a large GME in the monolayer NbX 2 (X= S, Se) normal to the plane, primarily driven by the orbital moments of the Bloch bands as opposed to the conventional spin magnetization, without any need for spin-orbit coupling.
