The field, instead of spreading in the way shown in Figure 16.4, is trapped in the extended ferro-magnetic circuit. The higher the susceptibility χ, the greater is the magnetisation and flux density induced by a given current loop, up to a limit set by its saturation magnetisation Ms. The...
every magnet exists in a self-generated field that has a direction such as to tend to demagnetize the specimen. This phenomenon is described by the demagnetizing factor. If the magnetic lines of force can be confined to the magnet and not allowed to escape into the surrounding medium, the de...
Herein, we theoretically demonstrate that simple metal (Ga and Al) substitutional atoms, rather than the conventional transition metal substitutional elements, not only stabilize the ThMn12-type SmFe12 and Sm(Fe,Co)12 phases thermodynamically but also fu
2). Worth noticing is also that elastic scattering – probed by ρ0 –is linked to the DOS at the Fermi energy. The field evolution of the KWR is therefore also reflected in the magnetic-field dependencies of A and ρ0 [Fig. 2c, d]. A similar decoupling of A and ρ0 has also ...
image of the magnetic field of a magnet is carried out, whereas, as we prove the ferrolens is free of these limitations and its far more advanced visualization capabilities is allowing it to show the quantum image with depth of field information, of the dipole field of a permanent magnet. ...
19,20 This peculiar magnetic order enables static and dynamical magnetoelectric effects21,22,23 and generates an electric polarization that can be enhanced or reversed by an applied magnetic field.20,24,25 Fig. 1 Illustration of the 120∘ Fe3+ spin order (a) and its helical modulation along...
In ourglossary, we define Br as, “the magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed.” That's at point #3. If we apply a current in the opposite direction, the magnetic field created by the current in the coil of wire opposes ...
The most widespread type of permanent-magnet instrument has a movable frame located in the field of a permanent magnet. When a current flows through the windings of the frame, forces are generated that produce torque. Current is supplied to the frame through springs, or tension members, which ...
While existing studies have focused on [Math Processing Error]NdNi5 crystals, amorphous thin-films of [Math Processing Error]NdNi5 are potentially important since they would be magnetically soft without magnetocrystalline anisotropy, meaning that small external magnetic fields could reverse the direction ...
conductance map directly reveals their difference in the electronic structure shown in the upper panel of Fig.1c, where the Co3Sn surface has a higher density of states at the bias voltage of 100 mV. From this map, we also find that the Co3Sn surface has detectable impurities induced ...
