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 ...

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.

Head saturation in magnetic recording
Journal of Applied Physics, 1988In this paper, we present two new head-modeling methods and discuss their use to study head-saturation effects. One is a nonlinear multiple-subdomain finite-element method, and the other augments the first by the use of a boundary-integral method to calculate the magnetic field’s density and gradient in the medium from potentials at the head-medium ...

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.

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.

Saturated high permeability magnetic shields
2016 ESA Workshop on Aerospace EMC (Aerospace EMC), 2016High permeability magnetic shields can be used in space to mitigate the effect of magnetic sources by several orders of magnitude. Nevertheless, the presence of significant amounts of ferromagnetic material on-board a spacecraft carries, by itself, a certain risk in terms of meeting magnetic cleanliness requirements.

Magnetic Saturation in Perpendicular Recording
IEEE Translation Journal on Magnetics in Japan, 1987Results of investigations involving calculations using the finite element method and experiments to determine the magnetic saturation during writing for both closed-circuit configuration single-sided heads and open-circuit configuration separated type heads are reported. The single-sided head reaches the same magnetic flux density as the separated-type
