The magnetic behavior of Co2+ and Co3+ ions doped into a well-known perovskite, SrTiO3, is investigated. We report the change in the effective magnetic moment of the cobalt ions, based on temperature-dependent magnetic susceptibility measurements, as a function of their formal valence. A low ...
The Co atoms are either nonmagnetic or carry a small moment in these compounds. The saturation moment of DyCo3B2at 5 K is smaller than the Dy3+free‐ion value. From161Dy Mössbauer studies, the measured hyperfine magnetic field at the Dy site is also observed to be smaller than the ...
The most stable spin state was Sz=4/2 for Fe-modified GNR, whereas Sz=3/2 for Co-case and Sz=2/2 for Ni-case. Atomic magnetic moment of Fe, Co and Ni were 3.63, 2.49 and 1.26 {\\\mu}B, which were reduced values than that of atomic Hund-rule due to magnetic coupling with ...
We present the results of an investigation of epitaxial Ag/bcc Fe/Ag(001) and Ag/fcc Co/Ag(001) sandwich structures in which we use polarized neutron reflection (PNR) as a direct probe of the absolute value of the magnetic moment per atom in order to test recent theoretical calculations ...
Thus, a net magnetic moment of around 4.7 μB is contributed by Co atoms in each compound and the same can be observed from Table 2. The large magnetic moments of Co3RhN, Co3PdN and Co3PtN are observed to be 6.20 μB, 5.20 μB and 6.21 μB, respectively. The observed values ...
In Table 2, we display the calculated magnetic moment of Ga, Mn and Co atoms within the muffin-tin (MT) sphere. For the AFM states, the magnetic moments of CoS and Mn1 are reduced compared to those of CoS−1 and Mn3. For the FM states, however, the magnetic moments of CoS and...
Magnetic measurements: A MPMS-3 system was used to determine the magnetisation hysteresis loops and the field cooled (FC) magnetisation as a function of temperature and applied magnetic field. From the magnetisation hysteresis loops, the coercive fields and saturation magnetisations were determined. For...
and VEA that, along with the increase of the CO molecules,the ability of detaching electrons is weakened and the ability of obtaining electrons is improved.The Mulliken charge analysis shows that the magnetic moment of Pd_5 is 2μ_B,however,Pd_5(CO)_n(n= 1~6) has no magnetic moment....
The Pt magnetization depth profile at a single buried Pt/Co interface was investigated by x-ray resonant magnetic reflectivity measurements. The asymmetry as function of angle of incidence has been measured in the Pt L-3-near-edge absorption. region at two energies. Observed asymmetry ratios in ...
The latter of these effects may indicate the presence of spin frustration in zero applied magnetic field. Muon spin rotation reveals an onset of short-range order below 3 K and confirms long-range order below T_N. 展开 关键词: antiferromagnetics thermal expansion thermomechanical effects muon ...
