Tweezing of Magnetic and Non‐Magnetic Objects with Magnetic Fields

Advanced Materials, 2017
Although strong magnetic fields cannot be conveniently “focused” like light, modern microfabrication techniques enable preparation of microstructures with which the field gradients – and resulting magnetic forces – can be localized to very small dimensions.

Covalent magnetism and magnetic impurities

Journal of Physics: Condensed Matter, 2013
We use the model of covalent magnetism and its application to magnetic insulators applied to the case of insulating carbon doped BaTiO3. Since the usual Stoner mechanism is not applicable we study the possibility of the formation of magnetic order based on a mechanism favoring singly occupied orbitals.

Persistent magnetic coherence in magnets

Nature Materials
When excited, the magnetization in a magnet precesses around the field in an anticlockwise manner on a timescale governed by viscous magnetization damping, after which any information carried by the initial actuation seems to be lost. This damping appears to be a fundamental bottleneck for the use of magnets in information processing.

Localized Magnetic Polaritons in the Magnetic Superlattice with Magnetic Impurity

Physica Scripta, 2004
The magnetic polaritons localized at the magnetic impurity layer in magnetic superlattice composed of the alternating ferromagnetic and nonmagnetic layers are investigated in the framework of the electromagnetic wave theory in the Voigt geometry. The general dispersion relation for localized magnetic polaritons is derived in the long-wavelength limit ...

Magnetic Monopoles in a Magnetic Universe

1984
Large scale coherence of a cosmological magnetic field, independently of its strength, is incompatible with any detectable monopole flux. Consequently, the controversial evidence1 of a coherent magnetic field up to a redshift z ≃ 2 infers the most severe cosmological bound on present number density (no) and fluxes (F) of magnetic monopoles: \( n_O < 2 \

Magnetism and Magnetic Materials

Physics Today, 1959
London : McGraw-Hill Publishing Co. Ltd. Pp. vi + 323. Price 77s. 6d. In recent years magnetism has made tremendous progress, and is still expanding on a widening front. Not only this but the impact of this new expansion on technology has been even more remarkable.

Magnetism, magnetics and microstructure

Ultramicroscopy, 1992
Abstract The relationship between magnetism, magnetics, and microstructure is discussed from the viewpoint of three different theoretical techniques. A dynamic micromagnetic theory is used to show that hysteresis can be accurately predicted from structural properties without the need for adjustable parameters.
