Magnetization Near Saturation in Polycrystalline Ferromagnets
Physical Review, 1941An important mechanism involved in the variation of the magnetization of ferromagnets near saturation is the rotation of the magnetization vector under the combined influence of the magnetic field and crystalline anisotropy torques. The effect of this mechanism in polycrystalline specimens has been calculated by Akulov and Gans; their result is ${M}_ ...

Self-saturation in magnetic amplifiers
Electrical Engineering, 1949SATURABLE reactors, in their simpler forms, have been used in controlling many types of equipment. As is known, control is effected by adjustment of the reactor impedance with d-c premagnetization. The a-c windings are so connected that no fundamental component of power-frequency voltage appears in the d-c control winding.

Selective saturation in magnetization transfer experiments
Magnetic Resonance in Medicine, 1994AbstractThe concept of magnetic saturation in single and binary spin systems is essential to the understanding of magnetization transfer experiments. This paper outlines the requirements for selective magnetic saturation of either of two spin pools contained in a mixture, both having identical chemical shifts. Following a brief discussion of saturation

Discrete tracks for saturation magnetic recording
Proceedings of the IEEE, 1963Discrete-track recording is a magnetic-recording method which employs a single-gap head and a discrete-track medium to increase the head-repositioning tolerance in saturation digital recording. A head with a conventional ring structure may be used. The recording medium consists of discrete magnetic tracks separated by nonmagnetic lands.

On the saturation field of magnets
Journal of Magnetism and Magnetic Materials, 2004Three small comments on the saturation field for magnetization curves of magnets are noted. The saturation field is generally formulted for magnets with translational invariance, so that one can calculate the coupling constant J of magnets from magnetization measurements up to the saturating point. An upperbound for more general cases and an inequality

Nuclear Magnetic Resonance Saturation and Rotary Saturation in Solids
Physical Review, 1955Nuclear spin-lattice relaxation times of ${\mathrm{Al}}^{27}$ in pure Al and ${\mathrm{Cu}}^{63}$ in annealed pure Cu have been measured with a nuclear induction spectrometer, by the method of saturation. The experimental values of ${T}_{1}$ are 4.1\ifmmode\pm\else\textpm\fi{}0.8 milliseconds for ${\mathrm{Al}}^{27}$ and 3.0\ifmmode\pm\else\textpm\fi ...

An algorithm for modeling saturating magnetic devices
Proceedings of the June 1970 design automation workshop on Design automation - DAC '70, 1970Nonlinear magnetic devices present complexities in circuit analysis that are not readily solved by conventional techniques. Two algorithms are developed that provide computer-aided techniques for the classical problems of saturation, hystersis and the multicircuit device.

Approach to Saturation in Inhomogeneous Magnetic Materials
Journal of Applied Physics, 1971The Néel theory of the approach to saturation in inhomogeneous magnetic materials is critically reviewed. It is found that the theory is rigorously applicable when the local saturation magnetization differs only slightly from its spatial average, but that this condition is not satisfied in porous materials or in material containing inclusions of a ...

Saturation Magnetization of Swaged Mn–Al
Journal of Applied Physics, 1962Two years ago remarkable properties were reported for a new alloy based on manganese and aluminum. The value for saturation magnetization in Mn=Al had been extrapolated to infinite magnetizing field and was given as 6200 gauss. Our measurements indicate that the extrapolated figure is too low.

Effects of magnetic saturation
1998Abstract In this chapter the effects of main flux saturation the equations required for the various implementations of vector control (e.g. rotor-flux-oriented control, magnetizing-flux-oriented control, stator-flux-oriented control) are discussed for both smooth-air-gap and salient-pole machines.
