Such a behaviour of M(T) is typical for the small particles system or for non-interacting magnetic clusters. The saturation magnetic moment mu(s) = 2.02 mu(B), determined from M(1/H) curves, agrees very well with the theoretical value. The Curie temperature T-c = 14.8 K were ...

For the other two samples, the FM signal is strong enough to avoid this effect even at the highest temperatures of the measurement. The moment scaled by the sample size to extract the average magnetization of the sample. This does not account for the expected different volume fractions of the...
Metal- molecule-metal junctions constructed by electro-migration have demonstrated the coupling between electric current and molecular magnetic moments, as well as the persistence of magnetic anisotropy within the device junction for [Mn12O12(O2CR)16(H2O)4] (Mn12), [Fe4(L0)2(dpm)6] and Tb...
When an electron in an atom or ion is unpaired, the magnetic moment due to its spin makes the entire atom or ion paramagnetic. The size of the magnetic moment of a system containing unpaired electrons is related directly to the number of such electrons: the greater the number of un...
The super-exchange interaction in the ferrite lattice makes the magnetic moment on the B-site stronger. This also makes the magnetic spins of the A and B sites next to each other antiferromagnetically connected. As seen in Fig. 10, the net magnetic moment of the present when R Cu-Mg-...
The method of measuring the magnetic moment (𝑇,B) gives the magnetization 𝑀(𝑇, B) at thermodynamic equilibrium and on a reversible path, which excludes metastable states and hysteresis phenomena, Maxwell’s relation is used to obtain information on entropy and heat capacity [28,29]. Fro...
Among transition metal ions, Mn2+ has received long-standing interest as a dopant in semiconductors14 because of its large spin magnetic moment (S = 5/2) and quenched orbital magnetic moment (L = 0). The latter implies reduced electron spin–lattice interactions, leading to ...
12). As Zn2+ is substituted for the T2+ species, the Zn ion displaces the Fe3+ ions from A to B sites because, among the most common ions, Zn2+ has the strongest chemical affinity for the A site. As a result, the net moment per formula unit (FU) of the compounds of the ...
The magnetic moment of Fe appears highly sensitive to the overall magnetic structure, the same as for the critical Fe2P [2,16–19]. In contrast to the large Mn moment of 2.6–3.02 µB, that of Fe is found to be more than twice as large in the ferromagnetic state (1.20 µB) ...
