Recently, it has been shown that the magnetic moment of iron oxide nanoparticles is strongly suppressed as their size decreases to <5 nm because of the reduction in the volume magnetic anisotropy and spin disorders on the surface of the nanoparticles (Scheme 2) [62], [63]. The spin canting...
The ferromagnetic state energy was calculated and compared with the local-moment-disordered (LMD) state energy for local density approximation (LDA) and LDA–SIC approximation. Mechanism of hybridization and interaction between magnetic ions in Sn0∙95Co0∙05O2 is also investigated. To explain...
Detailed investigations reveal that neighbouring tunnels which may be filled and unfilled lead to differences in the magnetic moment of Mn atoms in the apex site and plane site, thus breaking the balance of Mn-O-Mn bonds. This results in the ferromagnetic-like ordering. Furthermore, we can ...
However, they cannot explain thetemperature variation of the magnetic moments, if the magnitude ofeach magnetic moment is assumed to be determined by the molecularfield. 展开 关键词:magnetic moment α-Mn neutron diffraction DOI: 10.1143/JPSJ.64.1748 被引量: 2 ...
Interestingly the Co magnetic moment found corresponds to one third of the saturation magnetization of 3 mB for an isotropic S ¼ 3/2 cobalt ion. This result confirms that the ground state of the CoII ion is mainly built from MS ¼ ± 1/2 Table 2 | Values of the spin and orbital ...

The lanthanide atom Gd3+ is by the far the most frequently chosen metal atom for MRI contrast agents because it has a very high magnetic moment (u2=63 BM2), and a symmetric electronic ground state, (S8). Transition metals such as high spin Mn(II) and Fe(III) are also candidates due...
Local magnetic fields in a molecule-based optically chiral magnet [Cr(CN)6][Mn(S)-pnH(H2O)](H2O) [GN-(S)] and its enantiomer [GN-(R)] were studied by means of muon spin rotation and relaxation (μSR). A detailed analysis of μSR signals under a zero field observed in the magne...
• Paramagnetic and diamagnetic: these terms generally refer to the sign of the susceptibility as related to the direction of the external magnetic field, with paramagnetic referring to a positive susceptibility (net moment in the same direction as the applied field) and diamagnetic referring to...
