Spin and orbital moments in Fe3O4 We report a study of the spin moment in Fe 3 O 4 as a function of temperature using spin-dependent Compton scattering. Magnetic Compton profiles and spin ... JA Duffy,JW Taylor,SB Dugdale,... - 《Phys.rev.b》 被引量: 25发表: 2010年 CeRh{sub ...
Fe3+ is evenly distributed among the tetragonal and octahedral sites and is aligned antiparallel while Fe2+ is found exclusively on the octahedral site, resulting in a net magnetic moment of mneaagrnlyet4it μeBi.s It is generally considered that the orbital component of this net magnetic ...
The orbital motion of an electron around the nucleus can be equated to a current in a loop of wire having no resistance. The magnetic moment of an electron, due to this motion, is as (4.5)μo=(area of loop)(current in emu) According to Bohr's theory (1913) of atom the electron ...
The color scale corresponds to the amplitude of the magnetic moment fluctuations, with red depicting the largest amplitude and blue denoting zero amplitude. In Figure 5, we can observe how these modes change with respect to β. In Figure 5a, it is shown that mode R, which corresponds to ...
Yin and colleagues [46] doped dysprosium (the magnetic moment of Dy (10.6 µ B) was 3.5 times larger than Fe) into Fe3O4 nanoparticles and coated it with polyethylene alcohol on its outermost layer to improve the sensitivity of IOSNPs. The r 2 value was 123.2 s−1 mM−...
\({\tau }_{N}\)is the Neel relaxation time and\({\tau }_{B}\)is the Brownian relaxation time. Neel relaxation is attributed to alignment of the magnetic moment of the nanoparticle with the magnetic field without rotating the nanoparticle itself that results in heat production in the nanop...
The orbital and spin contributions to the magnetic moment of Fe in Fe3O4 nanoparticles were measured using X-ray magnetic circular dichroism (XMCD). Nanoparticles of different sizes, ranging from 5 to 11 nm, were fabricated via organic methods and their magnetic behavior was characterized by ...
