core loss
These examples involve quite different excitations which are respectively more characteristic of the properties of the bulk (core loss edges) or of the surface (plasmon modes).
      
The amount of sp3 hybridizised C atoms has been estimated by integration over the π* and σ* band ranges in the core loss spectra.
      
This value, when compared with the total length of recovered core allows quantification of core compaction or core loss.
      
A general increase of core compaction or core loss with core length can be observed.
      
The permeability, magnetic induction, and core loss of test specimens were optimal at their intermediate grain sizes.
      
(LC) core loss W15/50 of Epstein specimens was minimum at a grain diameter of approximately 150 μm, regardless of the silicon content.
      
Magnetic test results from coil centers show that, at a given cold band gauge, core loss is independent of percentage of cold reduction for both mill and laboratory processed samples.
      
Items affecting the core performance include: core loss, permeability, magnetostriction, insulation coating, strip flatness, thickness and width variations, camber, space factor, and physical characteristics.
      
The latest advance in very low core loss grain oriented silicon steels
      
By applying various magnetic domain refining techniques to high permeability, grain oriented silicon steel sheets (Orientcore HI-B), core loss can be greatly reduced.
      
When 7 mil Hi-B was treated with the heat-resisting technique, a core loss of about 0.22 w/lb (at 1.3 T/60 Hz) was obtained on a commercial scale.
      
Only one cell line was unscorable because of complete core loss.
      
CO2 laser processing for reducing core loss of cold-rolled grain-oriented silicon steel
      
Non-contact processing technique involving the use of CW and pulsed CO2 laser irradiation has been used for reducing the core loss of cold-rolled grain-oriented silicon steel.
      
These alloys have been characterized for various magnetic parameters like peak permeability, coercivity and core loss under changed annealing profile conditions.
      
This surface crystalline layer induces out-of-plane magnetic anisotropy in the amorphous ribbon and thus deterioration of the core loss.
      
The magnetic induction and core loss of test specimens deteriorated at a vanadium content of 0.016 wt%.
      
An overall improvement in the core loss was observed in the laser-scribed samples.
      
The best improvement in core loss was obtained in excimer laser scribing on the rolling direction and CO2 laser scribing in the transverse direction.
      
This nitrogenizing causes the deterioration of magnetic properties, such as core loss and induction.
