, is related to magnetic losses and is high at the

resonance frequency. For a speciﬁc composition range,

the values of magnetic anisotropy and magnetostric-

tion are reduced to near zero leading to a maximum

in complex permeability, as shown in Fig. 4.3-74. By

suitable control of the microstructure it is possible to fa-

vor the formation and mobility of fast-moving domain

walls. Consequently, the permeability of MnZn ferrite

is the highest among the ferrites with spinel structure.

However, the increase of the loss factor is consider-

ably enhanced with increasing frequency because of the

lower resistivity of MnZn ferrites compared to other

ferrite materials.

The properties of NiZn and NiCuZn ferrites are

designed for applications in the radio wave band. Fig-

4.3.4.2 Hard Magnetic Ferrites

A hard magnetic ferrite, also called ferrite magnet, is

a magnetic material based on iron oxide. The composi-

tion of the typical hard magnetic ferrite compounds is

shown in Table 4.3-54. M type material is used most

widely and BaO can be replaced by SrO.

Figure 4.3-76 shows the quasi-binary phase diagram

BaO–Fe

. The composition of the actual industrial

hard magnetic ferrite is selected to deviate slightly

from the stoichiometric composition in order to pro-

vide easy wetting and permit liquid-phase sintering. The

ferromagnetic phase SrO·6Fe

has a higher magne-

tocrystalline anisotropy constant K

and, thus, a higher

intrinsic coercive force

than the BaO-based com-

pound.

Table 4.3-55 shows the basic magnetic properties of

hard magnetic ferrites. The properties of actual products

are shown in Fig. 4.3-77. The demagnetization curves of

type YBM-9B, which have the best magnetic properties,

are shown in Fig. 4.3-78.

Comparing hard ferrites and rare earth magnets, the

ratio of remanence B

is about 1 :3, that of the co-

ercivity

is also about 1 : 3, such that the ratio of

the energy product (BH)

max

is about 1 : 10. From the

cost/performance point of view, the rare earth magnets

are used where weight and size are essential.

Mohs hardness, thermal conductivity, static

dielectric constant, dissipation factor (loss tan-

elastooptic and electrooptic coefﬁcients,

optical transparency range, two-photon

absorption coefﬁcient, refractive indices

and their temperature variation, dispersion

A large amount of the information in this section is

taken from the compilations of low- and high-frequency

properties of dielectric crystals in Landolt–Börnstein,

Group III, Vols. 29 and 30, especially Vol. 30b. Since

1992–1993, the date of publication of the ﬁrst of these

volumes, a large amount of new data on the physical

properties of dielectrics has appeared in the literature. In

particular, various linear and nonlinear optical properties

of new crystals in the borate family (BBO, LBO, CBO,

and CLBO) andof new organic crystals (DLAP, MNMA,

etc.) have been (re)measured in recent years. This sit-

uation has encouraged us to “refresh” the knowledge

about these crystals by adding new data from publi-

cations from the last decade. We have also included the

most commonly used isotropic materials. The criteria for

the selection of 124 dielectrics out of several hundred

were their wide range of application and the availability

of most of the above-mentioned data.

One of our aims was to produce a “reader-friendly”

compilation. For this purpose, all data on dielectrics

Part 4 4

818 Part 4 Functional Materials

are presented in a uniﬁed form in tables that are simi-

lar for both isotropic materials and crystals of various

symmetry classes. Moreover, all data for each par-

ticular material are collected together in one place.

Sections 4.4.1–4.4.2 serve as a brief introduction to the

various physical phenomena and to the deﬁnitions, sym-

bols, and abbreviations used. All numerical data are

presented in Sect. 4.4.4. The tables in this section are

arranged according to piezoelectric classes in order of

decreasing symmetry. Guidelines for searching for (and

ﬁnding!) the required parameter in these tables can be

found in Sect. 4.4.3.

The following table presents a list of the 124 different substances which have been selected to be described in

Sect. 4.4.4.
