On the saturation field of magnets

Journal of Magnetism and Magnetic Materials, 2004
Three 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

Approach to Saturation in Inhomogeneous Magnetic Materials

Journal of Applied Physics, 1971
The 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, 1962
Two 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.

Nuclear Magnetic Resonance Saturation and Rotary Saturation in Solids

Physical Review, 1955
Nuclear 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, 1970
Nonlinear 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.

The Effect of Dislocations on Magnetization Near Saturation

Physical Review, 1941
The effect of dislocations on the magnetization curve at high fields is calculated by direct use of dislocation theory. The deviation from saturation is assumed to be due to magnetostrictive forces, localized in the stress field about the dislocation rather than at the dislocation itself; their effect is more complicated than that of the simple "line ...

Effects of magnetic saturation

1998
Abstract 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.

The interpolar fields of saturated magnetic circuits

Journal of the A.I.E.E., 1927
In this note, the question of the effect of assuming infinite permeability in the iron on the accuracy of calculations of the interpolar fields in electric machines is studied. One can do this very easily by replacing the saturated by non-saturated poles, covered by an infinitely thin sheet of current giving the same tangential component of the field ...

On the saturation magnetization of Mn5 Ge3

Physics Letters A, 1973
Abstract New magnetization measurements of Mn5 Ge3 lead to a moment of 2.60 μB per Mn atom at 4° K. Instead of Kanematsu's scheme, the inverse distribution is found to be in better agreement with experiments.
