The experiments described in this paper arose from the desire of Sir Arthur W. Rücker to obtain, in connection with his researches on the nature of the Earth’s magnetic field, further data concerning the properties of such magnetic materials of natural origin as may he present in appreciable quantity in the Earth’s crust. Iron of cosmic origin contains nearly always an appreciable quantity of nickel, and the magnetic properties of this material, especially their variation with temperature, have received very little attention. Most of the published data are qualitative only, and from them no very definite conclusion can be drawn beyond the fact that meteoric iron appears to be of very variable permeability. It was, therefore, thought desirable to make a careful quantitative study of a typical example of such material.

Grain Sizes

Nickel-Iron nanocrystalline alloys with different grain sizes were fabricated by electrodeposition technique. In this study, influence of the grain size nanocrystalline NiFe deposits on saturation magnetization Ms and coercivity Hc was investigated. Alternating gradient magnetometer (AGM) with up to 10 kOe applied magnetic field was used to study the magnetic properties of NiFe film. The results showed that saturation magnetization Ms and coercivity Hc were affected by grain size variation. Increase in grain size increased the saturation magnetization. The largest grain size of 18.6 nm showed the highest Ms of 138 emu/g, while the smallest grain size of 7.2 nm showed Ms of 94 emu/g. Minimum coercivity of 3.847 Oe was observed for sample with 7.2 nm grain sizes. The coercivities decreased for smaller grain sizes.

Abstract METGLAS Alloy 2826 (Fe40Ni40P14B6) is a ferromagnetic, high permeability, nickel-iron metallic glass which, when appropriately annealed, yields a material similar to the higher nickel containing permalloys in magnetic properties. Alloy 2826 is a single phase, opaque metallic material with a glass-like structure obtained by a very rapid quench from the liquid state. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on forming and heat treating.

Microstructural Studies

The paper presents the results of structural and microstructural studies for the bulk Fe65Co10Y5B20 and Fe63Co10Y7B20 alloys. All the rods obtained by the injection casting method were fully amorphous. It was found on the basis of analysis of distribution of hyperfine field induction that the samples of Fe65Co10Y5B20 alloy are characterised with greater atomic packing density. Addition of Y to the bulk amorphous Fe65Co10Y5B20 alloy leads to the decrease of the average induction of hyperfine field value. In a strong magnetic field (i.e. greater than 0.4HC), during the magnetization process of the alloys, where irreversible processes take place, the core losses associated with magnetization and de-magnetization were investigated.

PS/CoPd Janus particles respond very sensitively to application of low external magnetic fields. Owing to the magnetic properties, the PS/CoPd particles may be used, for example, to sense the presence of weak magnetic fields as micro-magnetometers.

Face Centered

In this study, [Co/Ni]2/PtMn thin films with different PtMn thicknesses (2.7 to 32.4 nm) were prepared on Si/SiO2 substrates. The post-deposition perpendicular magnetic field annealing (MFA) processes were carried out to modify the structures and magnetic properties. The MFA process also induced strong interlayer diffusion, rendering a less sharp interface between Co and Ni and PtMn layers. The transmission electron microscopy (TEM) lattice image analysis has shown that the films consisted of face-centered tetragonal (fct) PtMn (ordered by MFA), body-centered cubic (bcc) NiMn (due to intermixing), in addition to face-centered cubic (fcc) Co, Ni, and PtMn phases. The peak shift (2-theta from 39.9° to 40.3°) in X-ray diffraction spectra also confirmed the structural transition from fcc PtMn to fct PtMn after MFA, in agreement with those obtained by lattice images in TEM. The interdiffusion induced by MFA was also evidenced by the depth profile of X-ray photoelectron spectroscopy (XPS). Further, the magnetic properties measured by vibrating sample magnetometry (VSM) have shown an increased coercivity in MFA-treated samples. This is attributed to the presence of ordered fct PtMn, and NiMn phases exchange coupled to the ferromagnetic [Co/Ni]2 layers. The vertical shift (Mshift = −0.03 memu) of the hysteresis loops is ascribed to the pinned spins resulting from perpendicular MFA processes.
