“…The surface skewness takes the value 0 and surface kurtosis takes the value 3 for a surface with a Gaussian height distribution. 48 The statistical analysis of the film surface showed that the kurtosis and skewness values were in the range of 3.877-15.183 and 0.4230-1.9014, respectively. The obtained surface skewness values (> 0) indicate the presence of a spiky surface with sharp peaks and low valleys in all films.…”

“…The obtained surface skewness values (> 0) indicate the presence of a spiky surface with sharp peaks and low valleys in all films. [48][49][50][51][52] The resulting surface kurtosis values (> 3) show that all film surfaces exhibit leptokurtic height distribution with sharp peaks. 50,53 Besides, the surface skewness and surface kurtosis increase slightly as the electrolyte pH is decreased from 4.7 to 3.9, and then increase sharply when the pH of the electrolyte is decreased from 3.9 to 3.2.…”

The composition, structural features, surface morphology, roughness parameters, particle size, and magnetic features of nanostructured Fe‐Co‐Ni deposits manufactured on conducting indium tin oxide‐coated glasses at various electrolyte pH values are studied. The deposit produced at low electrolyte pH contains slightly higher Fe and Co contents but lower Ni content compared to deposits fabricated at high pH values. Further composition analysis confirms that the reduction rates of Fe2+ and Co2+ are higher than the Ni2+ reduction rate. The films consist of nano‐sized crystallites with a strong [111] preferred orientation. The results also reveal that the crystallization of the thin films is affected by the electrolyte pH. Surface analysis shows that the deposit surfaces are composed of nano‐sized particles with different diameters. The mean particle diameter and surface roughness decrease as the pH of the electrolyte decreases. The effect of the electrolyte pH on the morphology is also discussed in terms of surface skewness and kurtosis parameters. Magnetic analysis shows that the resultant deposits have in‐plane hysteresis loops with low and close SQR parameters ranging from 0.079 to 0.108. The results also reveal that the coercive field of the deposits increases from 29.4 Oe to 41.3 Oe as the electrolyte pH decreases from 4.7 to 3.2.

Soft ferromagnetic permalloy (NiFe) thin films are promising for applications in spintronic devices because of their constituent electrical and magnetic properties. Electron beam evaporation and sputtering techniques have been used to deposit NiFe thin films. For in situ stacking of NiFe with functional complex oxides, the pulsed laser deposition (PLD) method is highly desirable. However, the growth of high‐quality NiFe (and non‐oxide thin films in general) by PLD remains a formidable task. Here, high‐quality NiFe thin films of various thicknesses on oxide/non‐oxide substrates with desirable magnetic properties by PLD at room temperature are reported. The magnetic properties are found to be strongly dependent on the laser fluence of the deposition process. The laser fluence of 4 J cm−2 produces the highest magnetization of ≈547 emu cc−1. The small coercivity (few Oersted) and sharp ferromagnetic switching behavior indicate uniaxial anisotropy with an easy axis along the in‐plane direction. In addition, thickness‐dependent magnetodynamics characterizations are studied via ferromagnetic resonance. These results offer significant insight into the PLD‐based development of thin metal magnetic films.
