A distinctive feature of this compound is the presence of temperature hysteresis at the transition to the ordered state (corresponding to a first-order magnetic phase transition) and of a spontaneous magnetic moment along thexaxis. The paramagnetic Curie temperatures are determined. The frequency–...
No such effects were observed for M=Al . The saturation magnetization, M S , decreases approximately linearly with increasing substitution of Al or Mn. The changes in the magnetization and magnetostriction can be understood on the basis of a decreasing 3d sublattice moment. 展开 ...
Meanwhile, the thermal motion destroys the regular orientation of the magnetic moment of the atoms, decreasing the spontaneous magnetization intensity. The magnetic hysteresis loops of the CNMF_6h at tem- peratures of 25uC, 40uC and 60uC are presented in Figure 6(c). The magnetic hysteresis ...
Using even longer tempering times, the magnetic moment decreased (decomposition of α'〧e16N2 to α〧e and γ'〧e4N). Only a very small amount of γ'〧e4N was formed after tempering at 120°C for one week. The average coercivity of the samples nitrided at 650–700°C is about 200...
At ambient pressure, YCo 9 Si 4 shows weak itinerant ferromagnetism below 25 K with an ordered moment of about 1.6 μ B / f . u . The temperature-dependent electrical resistivity exhibits below 10 K a power-law behavior R ( T ) = R 0 + AT n . The exponent n ...

The red shift at this moment was attributed to the formation and increasing Mn2+-Mn2+ ferromagnetic dimers. It is worth noting that only a small part of Mn2+ enters the lattice(Mn/Pb=11/2.7). Interestingly, with the increasing Mn2+ concentration, the PLQY and CRI of the produced compounds...

Photodegradation efficiency of the samples for MG dye enhanced from 13.6 to 61.1%. Introduction Ferrite nanoparticles (NPs) are ionic materials composed of a combination of metal oxides and iron oxides. They are classified into four distinct crystalline structures: spinel [1], garnet [2], hexagonal...
