“…This may be due to the anisotropy contributions brought by the randomly oriented crystallites or different phases present in the polycrystalline material. [83,84] The spectra of all the samples have been deconvoluted using Gaussian fitting of the absorbance spectra considering the contribution from Fe and respective iron oxides. An additional out of phase contribution may be due to the skin effect as discussed by Dyson [85] due to the different ratios of electron spin resonance time and electron diffusion time through the skin depth which, in turn, affects the shape of the spectrum.…”

Magnetocrystalline anisotropy is a crucial parameter that determines the suitability of magnetic material in a wide range of emerging applications. The law‐of‐approach‐to‐saturation (LAS), utilized to obtain the magnetocrystalline anisotropy from hysteresis loops, is not satisfactory for materials with cubic anisotropy as they are two orders higher than the bulk value. Herein, a modified formulation to LAS is presented, where the reduction in effective magnetic anisotropy (K) values due to Fe oxide phases in Fe particles over wide size ranges is accounted. The value of K decreases from 4.2 × 104 J m−3 for the Fe particles of average size 210 nm to 1.2 × 104 J m−3 for the 20 nm particles due to the increase in the iron oxide fraction with size reduction. The effective magnetic anisotropy obtained from the modified LAS has been validated from the ferromagnetic resonance studies for particles of the smallest size.

“…Rohan et al 258 added Ni II salts to an EL Fe bath formulated at pH 6.5 with citric acid and CH 3 CH(OH)COOH ligands and the strong reductant, DMAB, to deposit EL permalloy (i.e., NiFe alloy) films having oriented magnetic dipoles onto a Cu-coated Si substrate at temperatures exceeding 58 °C in the presence of a magnetic field. Most recently, Yaroslavtsev and co-workers 259 applied Pd catalyst onto a Cu mesh to plate Fe using a pH 11 bath containing Na 3 citrate and Na 2 EDTA ligands and arabinogalactan, a polysaccharide, as a reductant at 85 °C. The Fe-coated Cu fibers contain C inclusions resulting from arabinogalactan oxidation to produce tunable frequency-selective surfaces for EMI shielding applications.…”

The electroless plating of metals and their alloys, oxides, and chalcogenides represents a critically important technology for the automotive, aerospace, machine tools, and, especially, the electronics industries. Since the initial efforts involving the plating of industrially important metals, such as Ni, Co, Cu, Ag, and Au, in the mid-20th century, the process has evolved to encompass a growing number of elements. At the same time, this expansion in the palette of accessible metals has enabled progress in these industries and evoked new nonconventional applications. In this review, we collect and survey available electroless processes in aqueous and organic solvent systems for each element organized according to position in the Periodic Table as a resource for the reader. Examples illustrating progress in the field are presented and are described in sufficient detail to be useful and understandable for both the expert and nonexpert. Given the historical importance of electronics as a driver for development of electroless processes, examples are electronics-related where possible. However, we strive to also include examples of applications in nontraditional fields to provide the reader with a sense of generality available for electroless methods. The review closes with an outlook for the field and a challenge to scientists and engineers to adapt electroless processes for new applications to continue the growth of the field.
