“…50 The smaller crystallite sizes of NiFe 2 O 4 NPs as well as the presence of amorphous polymer on the particle's surface might account for the lower M s value. 51,52 This observation is also in accordance with the observed particle sizes in the electron microscopy study. The temperature-dependent magnetization of NiFe 2 O 4 NPs was investigated using zero field cooling-field cooling (ZFC-FC) measurements.…”

“…Soft magnetic materials, in contrast to hard magnetic materials, should have a minimum coercivity, minimum hysteresis losses, high saturation magnetization, and maximum values of permeability. At the moment, the most widely used soft magnetic materials are pure iron [39,104], electrical steels based on an Fe-Si system, permalloys [8], soft magnetic ferrites such as Fe 2 O 3 , Fe 3 O 4 [66,105,106], NiZn [101], and amorphous and nanocrystalline alloys based on cobalt and iron [8,33,[107][108][109][110].…”

Additive manufacturing is a very rapidly developing industrial field. It opens many possibilities for the fast fabrication of complex-shaped products and devices, including functional materials and smart structures. This paper presents an overview of polymer 3D printing technologies currently used to produce magnetic materials and devices based on them. Technologies such as filament-fused modeling (FDM), direct ink writing (DIW), stereolithography (SLA), and binder jetting (BJ) are discussed. Their technological features, such as the optimal concentration of the filler, the shape and size of the filler particles, printing modes, etc., are considered to obtain bulk products with a high degree of detail and with a high level of magnetic properties. The polymer 3D technologies are compared with conventional technologies for manufacturing polymer-bonded magnets and with metal 3D technologies. This paper shows prospective areas of application of 3D polymer technologies for fabricating the magnetic elements of complex shapes, such as shim elements with an optimized shape and topology; advanced transformer cores; sensors; and, in particular, the fabrication of soft robots with a fast response to magnetic stimuli and composites based on smart fillers.

“…As this field intensifies, the jumps become more pronounced, but in the final stages, the magnetization exhibits only slight Barkhausen jumps. Furthermore, given the substantial magnetic permeability and minimal saturation magnetostriction of the Co-based alloys, [9,10] vitrovac is also a promising candidate for magnetic shielding applications. The underlying reason for its pronounced soft magnetic properties can be traced back to Co-based grains, ranging between 2 and 20 nm, which are encapsulated within an amorphous Fe-rich matrix.…”

Thin and flexible materials that can provide efficient electromagnetic interference (EMI) shielding are urgently needed, particularly those that can be rapidly processed and withstand harsh environments. Cobalt‐based metallic glasses stand out as prime candidates due to their excellent soft magnetic properties, satisfactory shielding features, and mechanical properties. Herein, a recently developed technique is used to fabricate metallic glass microfibers from Co66Fe4Mo2Si16B12 alloy. The produced microfibers are characterized for their size and uniformity by scanning electron microscopy and their amorphous structure is confirmed by X‐ray diffraction (XRD) and differential scanning calorimetry (DSC). The cobalt‐based metallic glass microfibers show an EMI shielding factor that reaches five in the static regime and obtains an up to 25‐fold increase of the attenuation constant in the Ku frequency band. This performance originates from the combination of soft magnetic properties and excellent electrical conductivity. In addition, the flexible microfibers exhibit excellent hardness and elasticity making them suitable for EMI shielding of complex geometries. Their hardness and elastic modulus are measured by nanoindentation to be 11.31 ± 0.60 GPa, and 110.54 ± 11.24 GPa, respectively.
