Spin-glass freezing leads to a gradual increase in saturation magnetization (6.6 to 9.2 emu/g) at 10 K and a systematic coercivity enhancement (350 Oe to 1.3kOe) at 10 K. This finding clearly points out the effect of carbon substitution on the structure and magnetic properties of nickel carbide nanoparticles.
The saturation magnetizations of very pure iron and nickel have been measured absolutely by a force method at room temperature. The values are 217.6 and 55.1 emu/g (217.6 and 55.1 J T-1 kg-') respectively. The theory and reliability of the force method are investigated and discussed. New measurements have also been made by a relative method on tho same materials at temperatures …
23.09.2015· Spinel ferrite is the class of oxide materials with remarkable electrical and magnetic properties, which have been investigated and applied during the last few decades. Amongst all inverse spinel ferrites, the nickel substituted cobalt ferrite has been extensively studied in view of their good chemical and thermal stability, high electrical resistivity, magnetic anisotropy, high coercivity and ...
The magnetic properties of the initial permeability and the saturation induction characterize mainly the different available soft magnetic nickel–iron alloys. The nickel–iron alloys Magnifer 75, Magnifer 7904 and Magnifer 8105 with nickel contents between appr. 75 and 82% achieve a …
The Properties of Electroless Nickel Rolf Weil and Konrad Parker Electroless nickel deposits are used by many industries as functional coatings because they possess a unique combination of both corrosion and wear resistance. The ability to coat parts, regardless of their size, with a deposit of uniform thickness is another desirable property of electroless nickel. As is the case for ...

Magnetic Saturation Seen in some magnetic materials, saturation is the state reached when an increase in applied external magnetizing field H cannot increase the magnetization of the material further, so the total magnetic field B levels off. It is a characteristic particularly of ferromagnetic materials, such as iron, nickel, cobalt and their ...
Note that the U.S. five cent coin called a "Nickel" is made of 75% copper and 25% Nickel (Ni). Even though it contains Nickel (Ni), a ferromagnetic material, they aren't visibly attracted to magnets. In fact, they don't interact with magnets like many other non-magnetic materials.
Magnetic properties of maraging steels have been investigated as a function of nickel concentration. The alloys nickel content varied from 12 to 24 wt pct, while other alloying constituents were kept at a level maintained in the 18Ni-2400 MPA-grade maraging steel. The magnetic properties were determined following aging for 1 hour in the temperature range of 450 °C to 750 °C. In every alloy investigated, …
In contrast to what is observed for TOPO-protected nickel particles, the saturation magnetization of HDA-capped nanoparticles is comparable to that of bulk nickel, which demonstrates that the coordination of an amine ligand does not alter the magnetic properties of nickel. † LCC-CNRS. ‡ LPMC. § CIRIMAT. ‖ CEMES-CNRS. * In papers with more than one author, the asterisk indicates the name ...
Our range of soft magnetic materials comprises nickel-iron, ... as well as amorphous and nanocrystalline alloys. Thanks to their high magnetic saturation of up to 2.4 T, the cobalt-iron (CoFe) alloys VACOFLUX ® and VACODUR® are generally suitable for all applications where high flux density and minimum weight are required. introduction coMPosition And MAteriAl stAndArds Material composition ...
Most metals aren't magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium. Because Nickel (Ni) is ferromagnetic it is used in making Alnico magnets (consisting of aluminium, nickel, and cobalt). Note that the U.S. five cent coin called a "Nickel" is made of 75% copper and 25% Nickel (Ni). Even though it contains Nickel (Ni), a ferromagnetic material, they ...
Because of its magnetic properties, nickel is also part of Alnico magnets (made of aluminium, nickel, and cobalt). These magnets are stronger than rare-earth metal magnets but weaker than iron-based magnets. Cobalt. Cobalt is an important ferromagnetic metal. For over 100 years, cobalt's excellent magnetic properties have helped develop a variety of applications.
