37、OR APPLICATION AT MICROWAVE FREQUENCIES MEASURING METHODS FOR PROPERTIES 1 Scope This International Standard describes methods of measuring the properties used to specify polycrystalline microwave ferrites in accordance with IEC 60392 and for general use in ferrite technology. These measuring method
38、s are intended for the investigation of materials, generally referred to as ferrites, for application at microwave frequencies. Single crystals and thin films generally fall outside the scope of this standard. NOTE 1 For the purposes of this standard, the words “ferrite” and “microwave” are used in
39、a broad sense: by “ferrites” is meant not only magneto-dielectric chemical components having a spinel crystal structure, but also materials with garnet and hexagonal structures; the “microwave” region is taken to include wavelengths approximately between 1 m and 1 mm, the main interest being concent
40、rated on the region 0,3 m to 10 mm. NOTE 2 Examples of components employing microwave ferrites are non-reciprocal devices such as circulators, isolators and non-reciprocal phase-shifters. These constitute the major field of application, but the materials may be used in reciprocal devices as well, fo
41、r example, modulators and (reciprocal) phase-shifters. Other applications include gyromagnetic filters, limiters and more sophisticated devices, such as parametric amplifiers. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated
42、references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendment) applies. IEC 60050-221, International Electrotechnical Vocabulary (IEV) Part 221: Magnetic materials components IEC 60205:2006, Calculation of the effective par
43、ameters of magnetic piece parts IEC 60392:1972, Guide for the drafting of specifications for microwave ferrites 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60050-221 apply. 4 Saturation magnetization Ms4.1 General Saturation magnetization is a ch
44、aracteristic parameter of ferrite materials. It is widely used in theoretical calculations, for instance in computation of tensor permeability components (see IEC 60050-221). In a variety of microwave applications, saturation magnetization determines the lower frequency limit of the device, mainly d
45、ue to the occurrence of so-called low-field loss when the material is unsaturated. Licensed Copy: Wang Bin, na, Mon Sep 18 07:45:20 BST 2006, Uncontrolled Copy, (c) BSIEN 60556:2006 8 4.2 Object The object is to give two similar techniques for measuring saturation magnetization. These are the vibrat
46、ing coil method (VCM) and vibrating sample method (VSM). The vibrating coil method 112 has the advantages of easier sample mounting and simpler mechanical arrangement when measurements over a range of temperatures are required, particularly at low temperatures. The vibrating sample method is more ac
47、curate, given a similar degree of elaboration in electronic apparatus. The equipment needed in both cases is very similar and the calibration methods are identical. The same test samples can be used for either technique. 4.3 Theory When a sphere of isotropic magnetic material is placed in a uniform
48、magnetic field, the sphere becomes uniformly magnetized in the direction parallel to the applied field. The sphere now produces its own external magnetic field, equivalent to that of a magnetic dipole at the centre of the sphere and orientated parallel to the direction of magnetization. If a small d
49、etection coil (in practice a pair wound in opposition) is now vibrated at small amplitude, close to the sample sphere and in a direction at right angles to the applied field, a voltage es, will be induced in the coil, proportional to the rate of change of flux sdue to the sample at the mean coil position x0whose value is given by dtdxdxdNex=0ss(1) where N is the number of turns on the coil. The motion of the coil, in the x-direction,
