“…Fortunately, it has been proved that magnetic particles were recovered and regenerated after the removal of magnetic field. In addition, the magnetic mesh can work well under harsh environment resulting from the intrinsic properties of ferrites ceramics with excellent chemical stability and mechanical hardness [258][259][260][261].…”

Magnetic materials are of increasing importance for many essential applications due to their unique magnetic properties. However, due to the limited fabrication ability, magnetic materials are restricted by simple geometric shapes. Three-dimensional (3D) printing is a highly versatile technique that can be utilized for constructing magnetic materials. The shape flexibility of magnets unleashes opportunities for magnetic composites with reducing post-manufacturing costs, motivating the review on 3D printing of magnetic materials. This paper focuses on recent achievements of magnetic materials using 3D printing technologies, followed by the characterization of their magnetic properties, which are further enhanced by modification. Interestingly, the corresponding properties depend on the intrinsic nature of starting materials, 3D printing processing parameters, and the optimized structural design. More emphasis is placed on the functional applications of 3D-printed magnetic materials in different fields. Lastly, the current challenges and future opportunities are also addressed.

“…The soft-magnetic mesh has following functions: (i) ability to be held under a relatively low magnetic field (e.g., two small pieces of NdFeB permanent magnets without energy assumption) as a magnetic filter, and can be removed if the magnetic field is removed; (ii) enhance magnetic flux and increase magnetic field gradient; and (iii) its rigid surface can be used to capture magnetic nanoparticles for magnetic separation. In addition, the magnetic filter can work even under harsh environment because the ferrite possesses excellent chemical stability and mechanical hardness, instead of nylon and stainless steel mesh. − …”

Wastewater contaminated with heavy metals is a worldwide concern due to the toxicity to human and animals. The current study presents an incorporation of adsorption and low-field dynamic magnetic separation technique for the treatment of heavy-metal-contaminated water. The key components are the eco-fabricated magnetic filter with mesh architectures (constituted of a soft magnetic material (Ni,Zn)FeO) and poly(acrylic acid) (PAA)-coated quasi-superparamagnetic FeO nanoparticles (NPs). PAA-coated FeO NPs possess high adsorption capacity of heavy metal ions including Pb, Ni, Co, and Cu and can be easily regenerated after the adjustment of pH. Moreover, magnetic mesh filter has shown excellent collection ability of quasi-superparamagnetic particles under a magnetic field as low as 0.7 kOe (0.07 T) and can easily release these particles during ultrasonic washing when small magnets are removed. In the end, after one filtration process, the heavy metal concentration can be significantly decreased from 1.0 mg L to below the drinking water standard recommended by the World Health Organization (e.g., less than 0.01 mg L for Pb). Overall, a proof-of-concept adsorption and subsequent low-field dynamic separation technique is demonstrated as an economical and efficient route for heavy metal removal from wastewater.

“…Ferrites synthesized by different methods having the same size can show different cation distributions and hence different magnetic and electrical properties. In recent days, nanophase ferrites are synthesized by several methods such as sol-gel [11], microemulsion [14], chemical combustion route [7], microwave hydrothermal [15], precursor [16], and ball milling methods [17]. Among all the methods, the solgel method is the commonly used method due to feasibility and good control over particle size and homogeneity [18].…”

A series of magnesium-doped Ni 0.65−x Mg x Zn 0.35 Fe 2 O 4 (x = 0.00, 0.04, 0.08, 0.10, 0.12, 0.16) ferrites have been synthesized using sol-gel and solid-state techniques. Sol-gel-synthesized ferrites were sintered at 1000 • C/2 h whereas solid-state-prepared ferrites were sintered at 1250 • C/2 h. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) studies confirm the spinel phase, and cation ion distribution has been estimated for both the batches using these studies. Magnetic measurements indicate the increase of saturation magnetization (M s ) up to x < 0.10 and decreases for further increase in concentration of magnesium. The Curie temperature of the samples was found to be decreasing with increase in concentration of Mg 2+ ions in both the batches.
