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 ...

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.

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.

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 ...

Printed Magnetic FePt Nanocrystal Films

ACS Applied Materials & Interfaces, 2009
Patterned monolayers and multilayers of FePt nanocrystals were printed onto substrates by first assembling nanocrystals on a Langmuir-Blodgett (LB) trough and then lifting them onto prepatterned polydimethylsiloxane (PDMS) stamps, followed by transfer printing onto the substrate. Patterned features, including micrometer-size circles, lines, and squares,

Magnetic Molybdenum Disulfide Nanosheet Films

Nano Letters, 2007
Bulk molybdenum disulfide is known to be a nonmagnetic material. We have synthesized edge-oriented MoS2 nanosheet-like films that exhibit weak magnetism ( approximately 1-2 emu/g) and 2.5% magnetoresistance effects with a Curie temperature of 685 K.

Magnetic Mesoporous Photonic Cellulose Films

Langmuir, 2016
Novel hybrid materials of cellulose and magnetic nanoparticles (NPs) were synthesized and characterized. The materials combine the chiral nematic structural features of mesoporous photonic cellulose (MPC) with the magnetic properties of cobalt ferrite (CoFe2O4). The photonic, magnetic, and dielectric properties of the hybrid materials were investigated

Anomalous Magnetic Films

Journal of Applied Physics, 1962
A study of three types of anomalous nickel-iron magnetic films has been made: high coercive-force films, which have unusually large hysteresigraph values of wall and rotational coercive forces; rotatable initial-susceptibility films, for which the value of the initial susceptibility as found from low-field hysteresigraph measurements is determined by ...

Magnetic-film memories: A survey

1960 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1960
An analysis is made of the modes of magnetization reversal and rotation in thin ferromagnetic films. The ways in which the various modes can be employed for destructive and non-destructive memories are discussed and their performance limitations considered.

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 ...
