Question

谁帮忙翻译一下论文的一部分？物理方面的，紧急，明天中午之前！！

第五页by any fabrication technique, e.g. hot pressing of exactly
stoichiometric material. For YIG, specifications from
device requirements and observed processing average
values are now converging on 20Oe, implying very low
levels of porosity and second phase materials, of around
0.2% total (Fig. 9).
A corresponding figure for CaVIn/Zr, with a K1/Ms
of close to 0 and a Curie temperature of 170–200 _C,
would be close to 3 Oe, depending on 4pMs (Fig. 8).
This would be difficult to achieve in practical manufacturing
because of the relatively complex chemistry of
this type of material, and so they may not be the best
choice for low IMD, even if their lower resonance linewidth
is an advantage for insertion loss.
6. Spinel and hexagonal ferrites
At 1–2 GHz, spinel ferrites are not used for junction
or linear devices because of their high Ms below resonance,
creating low field losses, or above resonance
because of their high linewidth. NiZn spinels are, however,
used as absorbers from 100 MHZ to 10 GHz in the
broad absorption peak associated with domain resonance
and the drop in permeability from lower frequency,
usually referred to as low field loss. These
absorbing properties can be used for both RF and high
speed digital applications at Gigabit rates. Their use as
inductors is limited to a few hundred MHz because their
permeability approaches unity just above 1 GHz, referred
to as the Snoek limit.
Hexagonal ferrites, because of internal anisotropy
fields, have significantly higher limits, opening up the
possibility of ferrite inductors in the 1 to 2 GHz
region,13,14 and special types of antennas, where _ >"r,
allowing impedance matching into free space, provided
the magnetic losses can be pushed out of the frequency
of interest by compositional adjustment of the relaxation
induced absorption peaks. These materials have
become known as a class of meta-materials, although
not strictly meeting that definition. Absorbers with
absorption peaks well above 10 GHz can be realized
from the same type of materials.
These materials in powder form are being used in
absorber paints, or when incorporated into plastics, as
moldable shapes, for example sheets of RF and high
speed data circuit leakage absorbers.
