A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Simple equations of effective demagnetizing factors N x e and N y e for use in Kittel's ferromagnetic resonance (FMR) formula have been derived for the first time. The effective demagnetizing factors are derived from anisotropy energy (G) and a static field direction expressed by a spherical coordinate system (θ,).Using the equations, the resonance equation at every direction can be easily.

This lecture will introduce basic domain theory and magnetic hysteresis. We will focus on strong ferromagnets for which the continuum (micromagnetic) approximation is useful. We will discuss how domain structures form and describe quasi-static processes relevant for hysteresis curves [1,2], touching on topics such as hard and soft materials. CTII1COK JII1TEPATYPhl I.

A general theory concerning the properties of magnetic materials having a nonuniform saturation magnetization is developed. In this theory, the local saturation magnetization and the local exchange interaction are assumed to vary in an arbitrary manner throughout the sample.

It is further assumed that a dc magnetic field is applied which is sufficiently large to magnetize the sample. Abstract. All materials interact with externally applied magnetic fields. When the constituents (atoms, molecules, or ions) of a material do not possess a permanent magnetic dipole moment, the interaction of the material with the magnetic field is rather weak and a sample of such a material is repelled from the regions of high magnetic field (diamagnetic behavior).

The temperature dependence of the ferromagnetic resonance linewidth of highly polished single‐crystal spheres of EuS was measured in the range from ° to 30°K, using standard microwave techniques at a frequency of GHz.

The linewidth increases from ∼5 Oe at °K to ∼ Oe at the Curie point, and continues to increase in the paramagnetic range to a value of Oe at 78°K. A new mechanism for magnon‐phonon relaxation process in ferrimagnetic insulators (e.g., YIG) is proposed which involves direct coupling of the magnons of various spin‐wave modes with phonons of the transverse optical modes.

This direct interaction emanates from the near‐zone magnetic field associated with the transverse optical modes of vibrations in ionic lattices. The dependence of the uniform precession amplitude and susceptibilityχ″ at ferromagnetic resonance on the high-frequency fieldh is discussed on the basis of an equation for the energy balance and classical equations for the spin wave amplitudes.

The dependenceχ″ (h) is first determined in the lowest non-linear approximation. According to these calculations, the initial decline of the. University and college departments of physics traditionally do not include advanced courses in magnetism in their curriculum.

Therefore we offer the reader this short review chapter presenting necessary data on magnetically ordered dielectrics. This saves the reader the necessity of referring to many books on magnetism [–13].
