摘要

The characterization of the magnetic properties of a material involves a number of different measurement techniques. The types of measurement appropriate for a particular magnetic material depend, first of all, on the size and shape of the sample under studies. The characterization of the samples used in magnetic recording investigations is complex and even the simplest of measurements require careful interpretation. In this review emphasis is placed on experimental techniques used for characterization of magnetic thin films, magnetic wires and small particles. The measurements of the following intrinsic material parameters will be discussed: 1. Exchange constants (including interlayer coupling) 2. Saturation magnetization 3. Anisotropy constants 4. Magnetostriction constants The following experimental techniques will be discussed in details: 1. Magnetometric techniques (including torque and SQUID magnetometry) 2. Ferromagnetic resonance, spin-wave resonance, strain modulated ferromagnetic resonance and nuclear magnetic resonance 5. Magnetostriction techniques (direct and indirect) Many of these experimental techniques can be used to measure different magnetic material parameters. Typical example is ferromagnetic resonance which yields information on exchange, magnetic anisotropy, magnetostriction and the damping parameters. Magnetometric techniques can be used to determine magnetization but also anisotropy, magnetostriction and the exchange constants. The subject of this review is very broad and can include many different examples. The present paper is focused mainly on pure magnetic measurement techniques (only exceptions are strain measurement techniques related to magnetostriction measurements). Because of limiting space we are not going to consider very powerful optical and magnetooptical techniques and for these techniques we refer to other review papers published in this proceeding. Previous reviews of magnetic measurement techiques can be found in[1-5].
