How does the magnetic properties of NiMnSn ribbons change with Co doping?5 answersThe magnetic properties of NiMnSn ribbons undergo significant changes with Co doping. Co substitution for Ni in Mn50Ni41−xIn9Cox ribbons enhances ferromagnetic coupling, leading to an enlarged magnetization difference across the martensitic transformation and increased magnetic entropy change. Additionally, in Ni45Fe5-XCoXMn40Sn10 ribbons, Fe substitution by Co alters the magnetic behavior due to increased lattice strain and magnetic strain from a high antiferromagnetic fraction. Moreover, the magnetic properties of Ni48Co1.5Mn35Sn15.5−xSix alloys are influenced by Si substitution, affecting the martensitic transition temperature and hysteresis loss. These findings collectively demonstrate that Co doping plays a crucial role in modifying the magnetic characteristics of NiMnSn ribbons, impacting factors such as magnetization, magnetic entropy change, and magnetic behavior across structural transformations.
What are the key findings of rare earth doped Ni-Co mixed ferrites?4 answersRare earth doped Ni-Co mixed ferrites have been studied for their structural, magnetic, and optical properties. The addition of rare earth ions such as Dy3+, Tb3+, Ce3+, Gd3+, Ho3+, Y3+, Sm3+, La3+, and Yb3+ has been investigated in various compositions of Ni-Co ferrites. The studies have shown that the rare earth doping affects the crystal structure, morphology, chemical bonding, and magnetic properties of the ferrites. The substitution of rare earth ions has been found to increase the remnant magnetization, coercivity, and saturation magnetization of the ferrites. The rare earth doping also influences the optical properties, with changes observed in the direct bandgap and photoluminescence emissions. Additionally, the rare earth doped Ni-Co ferrites have shown potential applications in stress/torque sensors, magneto-optical devices, water purification, and other related uses.
What is the properties of n-doping carbon?5 answersN-doping carbon has various properties. N-doped TiO2/carbon composites showed changes in structural and surface characteristics, improving their adsorption but decreasing photocatalytic efficiency. Carbon-coated Cu nanocomposites with N-doping achieved enhanced dielectric loss in both microwave and THz bands. Nitrogen-doped carbon quantum dots (N-CQDs) derived from biomass showed significant enhancement in fluorescence emission properties compared to pure glucose-derived CQDs without nitrogen doping. Nitrogen-doped carbon materials with a high nitrogen content and uniform distribution exhibited excellent electrochemical performance in lithium-ion batteries and sodium-ion batteries. Carbon nano-onions (CNOs) prepared with nitrogen self-doping showed good fluorescence performance, with stable blue light emission that could be used for data encryption and decryption.
What are the effects of Mn on the mechanical properties of quenched and tempered steel?4 answersThe addition of Mn to quenched and tempered steel has various effects on its mechanical properties. In the case of 3 wt% Mn steel, increasing the partitioning time during heat treatment resulted in a decreased volume fraction of martensite phase and an increased volume fraction of retained austenite phase, leading to improved Vickers hardness and impact toughness. For 9Cr2WVTa steels, the tensile properties at room and high temperatures were not significantly affected by Mn content, but the impact toughness slightly reduced with higher Mn content. However, the high temperature oxidation resistance was significantly improved with an increase in Mn content, attributed to the formation of Mn-oxides and Cr-rich oxides. In the case of high-Mn oxide-dispersion-strengthened (ODS) steel, the addition of Mn resulted in the transformation of the microstructure, leading to higher room-temperature tensile ductility and higher Charpy impact energy at cryogenic temperatures.
Co and Ni doped SrFe12O19 crystal structure?5 answersCo and Ni doped SrFe12O19 crystal structure has been studied in several papers. Xavier Obradors et al. demonstrated the structural isomorphism of SrFe12O19 with BaFe12O19, showing that the bipyramidal Fe ions have a fast diffusional motion within a quasiharmonic double-well potential as in BaFe12O19. F. Sánchez-De Jesús et al. investigated the influence of milling parameters, hematite excess, and annealing temperature on the magnetic properties of SrFe12O19. They found that mechanical milling followed by annealing at low temperature (700 °C) promotes the complete structural transformation to Sr-hexaferrite phase. Therefore, the crystal structure of Co and Ni doped SrFe12O19 is likely to be similar to that of SrFe12O19, with some structural differences due to the doping elements.
What are the effects of zinc manganese doping on the magnetic properties of cobalt?5 answersZinc manganese doping has significant effects on the magnetic properties of cobalt. The saturation magnetization (Ms) decreases with increasing Mn2+ concentration due to the decrease in crystallite size and the non-magnetic nature of Mn2+. The addition of manganese ions also affects the hysteresis of the cobalt ferrite, resulting in a small hysteresis at room temperature. The magnetic moments in the mixed-spinel Zn1−xMnxFe2O4 nanoparticles show Yafet-Kittel type magnetic ordering, with significant variations between experimental and theoretical magnetic moments. Furthermore, the magnetic characteristics of the doped ferrites are evaluated using a vibrating sample magnetometer (VSM), revealing ferrimagnetic and soft magnetic behavior. Overall, zinc manganese doping influences the magnetic properties of cobalt ferrite, affecting parameters such as saturation magnetization, hysteresis, and magnetic ordering.
