In this study, a eutectic composition of Ni₄₈Co₁₀Mn₃₂Sn₁₀ with a fully L2₁/γ lamellar structure significantly improves mechanical properties, reaching 1950 MPa fracture strength and 20.5 % ductility. However, the desired magnetocaloric effect (MCE) is completely inhibited due to a strong Kurdyumov and Sachs orientation relationship (K-S OR) between eutectic phases. To overcome these challenges, a solution to precipitate primary L2₁ phase is proposed. This approach breaks the K-S OR by promoting epitaxial growth of the L2₁ eutectic phase on the primary L2₁ phase. Consequently, the hypoeutectic Ni₄₈Co₈Mn₃₄Sn₁₀ composition achieves an excellent balance between MCE and mechanical properties, with a maximum magnetic entropy change of 10.13 J kg⁻¹ K⁻¹ under 5 T magnetic field, 1894 MPa fracture strength, and 18.4 % ductility.

Hence, increased power density, magnetic performance, and thermal margin during PCE operation is of critical importance to the ever-present need to make these components smaller and more efficient. This can occur by incorporating new advanced magnetic (AdvMag) materials in their designs that will improve the PCE performance compared to the currently used magnetic materials consisting primarily of laminated electrical steels. Our current work is dedicated to a comprehensive comparison of these different new advanced magnetics materials and how they can be used to improve both DC (low frequency) and AC performance of inductors and transformers, leading to much more efficient PCE devices. We analyze the effects of these emerging materials both theoretically and by using full-wave simulations. We conclude that amorphous alloys and new light-weight nanocrystalline magnetic materials can serve as suitable substitutes of steel in laminated transformer designs. In addition, ferrites can also improve inductor and transformer operation as they possess excellent thermal properties, reduced weight, and low loss.

In this study, CoFe&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt; (CFO) was synthesized using the solid-state method, and its structural, morphological, elastic, and magnetic properties were examined at sintering temperatures of 1000 °C, 1100 °C, and 1200 °C. XRD analysis confirmed that the synthesized ferrite crystallized in a single-phase cubic spinel structure with an Fd-3 m space group. Rietveld analysis was utilized to extract information on the lattice constant, internal strain, and cation distances. Scanning electron microscopy (SEM) revealed the morphology of the samples, with grain sizes measured using ImageJ software showing a temperature-dependent increase from 0.5 to 2.98 μ m. The FTIR spectra of the CFO revealed characteristic vibrational bands associated with spinel ferrite functional groups, with distinct bands observed at approximately 475 cm&lt;sup&gt;−1&lt;/sup&gt; and 590 cm&lt;sup&gt;−1&lt;/sup&gt;, confirming the formation of the spinel ferrite structure. Vibrational bands corresponding to tetrahedral and octahedral positions in the FTIR spectra were used for calculating the elastic constants and Debye temperature. Magnetic measurements on CFO revealed that the saturation magnetization increases from 79 emu/g to 106 emu/g upon sintering. This increase is attributed to the enhancement of bond angles θ&lt;sub&gt;1&lt;/sub&gt; and θ&lt;sub&gt;2&lt;/sub&gt;, which strengthens the super-exchange interactions between the A and B sites. The real part of magnetic permeability (μ’) of CFO remains stable up to 100 MHz, marking its utility zone, and then gradually decreases at higher frequencies due to relaxation and resonance effects, indicating strong magnetic performance. DFT calculations using CASTEP revealed that the distribution of magnetic cations between tetrahedral and octahedral sites plays a critical role in determining the electronic structure, bandgap energy, and magnetic moment of the CFO. The electronic band structure, TDOS, and PDOS reveals that CoFe&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt; bulk material possesses a direct band gap of 0.63 eV in the spin-down channel and an indirect band gap of 1.08 eV in the spin-up channel.
