Spin valves work because of a quantum property of electrons (and other particles) called spin. Due to a split in the density of states of electrons at the Fermi energy in ferromagnets, there is a net spin polarisation. An electric current passing through a ferromagnet therefore carries both charge and a spin component. In comparison, a normal ...
A mop handle consists of a long piece of wood or metal tubing fitted with a specific attachment for the mop head. The handle can be attached the mop head by means of: clamp; hanger (with strands doubled over the hanger) plastic claws (attached to the strands) pouch (as with many professional flat mops) screwing (as with the classic yarn mop)
A transformation of spin currents consisting in interchanging (swapping) of the spin and flow directions (q ij → q ji) was predicted by Lifshits and Dyakonov. [10] Thus a flow in the x-direction of spins polarized along y is transformed to a flow in the y-direction of spins polarized along x. This prediction has yet not been confirmed ...
When the handle is pushed down, the shaft slides into pawls in the tubular stem, turning the bit. Most screws are "self locking" and axial force on the shaft will not turn the screw. This self-locking property is one reason for the very large use of the screw in threaded fasteners such as wood screws, sheet metal screws, studs and bolts ...
The Magnus effect is not responsible for the movement seen in conventional swing bowling, [30]: Fig. 4.19 in which the pressure gradient is not caused by the ball's spin, but rather by its raised seam, and the asymmetric roughness or smoothness of its two halves; however, the Magnus effect may be responsible for so-called "Malinga Swing", [31 ...
In this EMC experiment, a quark of a polarized proton target was hit by a polarized muon beam, and the quark's instantaneous spin was measured. In a polarized proton target, all the protons' spins take the same direction, and therefore it was expected that the spin of two out of the three quarks cancels out and the spin of the third quark is polarized in the direction of the proton's spin.
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, [1] stiff nut [1] or elastic stop nut, [2] is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. [ 2 ]
Injection locking and injection pulling are the frequency effects that can occur when a harmonic oscillator is disturbed by a second oscillator operating at a nearby frequency. When the coupling is strong enough and the frequencies near enough, the second oscillator can capture the first oscillator, causing it to have essentially identical ...
