Millimicrosecond Magnetization Reversal in Thin Magnetic Films

IBM Journal of Research and Development, 1959
A special pulse equipment including a pulse sampling oscilloscope with an overall response time of 0.35 mμsec for the observation of the millimicrosecond flux reversal in thin permalloy films is described. Output signals as short as 1 mμsec have been obtained and are discussed with respect to the underlying reversal processes.

Thin film magnetism

Proceedings of the IEEE, 1990
New developments in thin-film magnetism are reviewed with an emphasis on the ultrathin regime. Relatively simple metallic systems in overlayer, sandwich, and superlattice configurations are covered. Sample fabrication, characterization, and magnetic measurement techniques are outlined, highlighting some of the more modern experimental innovations ...

Magnetic properties of amorphous magnetic films coated with Permalloy films

IEEE Transactions on Magnetics, 1978
The magnetic properties of ferrimagnetic amorphous films (Gd-Co, Gd-Co-Au) with perpendicular anisotropy, coated with Permalloy films with the in-plane anisotropy, have been investigated. Coating with Permalloy film or transition metal films (Fe, Ni, Co) lowers the compensation temperature in the amorphous films about 5°C compared with that of single ...

Magnetism: Magnetic films and surfaces

Physics Bulletin, 1986
The 11th international colloquium on magnetic films and surfaces (ICMFS) was held at Asilomar State Park, USA, on 2–6 September 1985. This satellite conference of the much larger international conference on magnetism (ICM), which was held the previous week in San Francisco, provided an overview of the field of magnetic films and surfaces.

Microwave Magnetic Film Devices

2000
Publisher Summary This chapter discusses the applications of magnetic films in microwave devices. Magnetic film microwave devices are based on a broad class of ferrimagnetic materials commonly referred to as “ferrites.” Both ferro- and ferrimagnetic materials exhibit the hysteresis effect, which is a nonlinear relationship between the applied ...

Magnetization creep in magnetic films

IEEE Transactions on Magnetics, 1966
Magnetization reversal in planar magnetic films can occur for field amplitudes well below the static threshold. Repeated field transitions parallel to a film's hard axis in the presence of an easy-axis field can cause slow motion or creeping of the domain boundaries.

Magnetization and magnetic anisotropy in Ni/Pd multilayer films

IEEE Transactions on Magnetics, 1999
We have investigated magnetization and magnetic anisotropy in Ni/Pd multilayer films, prepared by dc magnetron sputtering at 7 mTorr Ar sputtering pressure. Interestingly, enhanced magnetization was found in this system, due to the polarization of Pd.

Magnetism and magnetic heterogeneity of EuO films

Journal of Magnetism and Magnetic Materials, 1985
Abstract The results of synthesis and the study of magnetic parameters of EuO films and solid solution of Eu1 − xSmxO at low temperature are given. Magnetic anisotropy of the film forms influencing the occurence of the magnetic heterogeneity effect in the easy and hard directions of the magnetization is determined.

Magnetic Shielding by Superconducting Films

Journal of Applied Physics, 1962
The magnetic field distribution and supercurrent density are calculated exactly by means of the Maxwell-London equations for the case of an ideal superconducting spherical shell immersed in a steady uniform magnetic field. It is shown that the magnetic field is strongly attenuated by the spherical shell even if the shell thickness is as small as 1000 A.

Magnetic Tweezers with Magnetic Thin Films

Japanese Journal of Applied Physics, 2011
Magnetic tweezers consisting of a 75×0.65×0.3 µm3 silicon oxide cantilever and a 72×13×0.3 µm3 silicon oxide plate deposited with magnetic thin films are fabricated and placed under various magnetic fields to observe their flexure. The principle of the magnetic tweezers is magnetic torque on condition that the high shape magnetic anisotropy is ...
