Preparation of magnetic alloy particles from metal and phthalate ions in dimethyl sulfoxide

H. Johnson IEEE Transactions on Magnetics, 1972

Magnetic particles suitable for recording media are prepared by dissolving a metal salt (nickel, cobalt, iron, or their mixtures) in dimethyl sulfoxide to form a metal complex which is reacted with the phthalate ion (also dissolved in dimethyl sulfoxide) to produce the metal phthalate which precipitates with addition of water. The supernatant liquid is decanted, leaving the precipitate, which is ...


Charge Deposition Profiles near Irradiated Material Interfaces

A. R. Frederickson IEEE Transactions on Nuclear Science, 1976

Charge deposition profiles in thin planar layers of aluminum, tin and tantalum next to various combinations of thick layers of aluminum, copper, tin and lead have been measured under cobalt 60 irradiation. The gamma ray beam is collimated and its energy spectrum is measured. The gamma intensity is accurately determined so that the absolute charge deposition can be related to ...


Comparison between a magneto-optical method and Fannin's technique for the measurement of Brown's relaxation frequency of ferrofluids

B. Payet; A. Siblini; M. F. Blanc-Mignon; G. Noyel IEEE Transactions on Magnetics, 1999

A magneto-optical method, conceived in our laboratory to measure Brown's relaxation frequency of ferrofluids, is compared with Fannin's technique based on impedance measurements (slit toroid). We have developed a complete theory and an experimental setup of the first method and have briefly described the second one. We present a study of Brown's relaxation of cobalt ferrite Fe2CoO4 in different carrier ...


Magnetic Moment and Curie Temperature in Amorphous Co-R Alloys

Yang Xing-Bo; S. Ishio; T. Miyazaki IEEE Translation Journal on Magnetics in Japan, 1990

The magnetic properties of amorphous Co100-xYx (50 ≤ x ≤ 70) alloys prepared by a melt-quenching method were studied. Based on the results derived from the Co-Y alloys, the magnetic moment of Co and the Curie temperature in amorphous Co100-xRx (R = Pr, Nd, Sm, Gd, Dy, Er) alloys are discussed. The Co atoms no longer sustain a moment when ...


Mixed anisotropies in small ferromagnetic particles

K. O'Grady; R. Chantrell; E. Wohlfarth IEEE Transactions on Magnetics, 1984

Low temperature magnetic measurements have been carried out on a system of fine cobalt particles in a solid matrix. Samples frozen in a large applied field were found to exhibit the shifted hysteresis loop indicative of exchange anisotropy. The magnetic properties of the system were found to be determined by the mixture of the unidirectional exchange anisotropy and the predominant ...

  • Core Laminations and Their Insulation

    This chapter covers a class of materials known as ferromagnetics. They are very strongly magnetic and include iron, nickel, cobalt, and some alloys. For motor and generator applications, there are two ways to obtain a magnetic field with ferromagnetic materials. It can be created either by electric currents, as in electromagnets, or by permanent magnets. We focus on the materials, processes, and insulation of electromagnets.
