The total magnetic moment of Mn2+ is found to be 2.27(7) μB. The antiferromagnetic behaviour was confirmed from magnetisation measurements. The transition from a paramagnetic to an antiferromagnetic state takes place at 13.0±0.1 K. PACS 61.12.Ld; 75.25.+z Keywords Neutron diffraction; Double...
The magnetism of Fe2MnAl and Mn2FeAl compounds are studied by first principles. Evolutions of magnetic moment of Fe2MnAl display distinct variation trends under pressure, showing three different slopes at different pressure intervals, 0~100 GPa, 100~250 GPa, 250–400 GPa, respectively, and...

Magnetic moment, also known as magnetic dipole moment, is the measure of the object's tendency to align with a magnetic field. The objects have a tendency to place themselves in such a way that the magnetic moment vector becomes parallel to the magnetic
moment of any element, which is expected to have a good enhancement effect on relaxation rates17. As an essential human dietary element, Mn also has essential roles in cell biology, and Mn2+can be used for functional brain imaging owing to the ability of Mn2+to enter cells through Ca2+...
Die magnetischen Momente der beiden kristallographischen Lagen sind deutlich verschieden fr alle Temperaturen unterhalb von T x, wobei Ml das wesentlich kleinere Moment aufweist. Bei 2 K sind beide Momente gegenber dem Wert des reinen Spinmagnetismus reduziert. In Co2SiO4 sind die Momente der...
Also, the addition of Zinc ferrite into an inverse spinel structure such as Fe3O4 NPs is found to raise the net magnetic moment of the resulting mixed spinel structure which in turn enhances the T2 relaxivity and improves the detection sensitivity of MRI (Barcena et al., 2008). 2.5 The ...
Relation of magneto-optical properties of free excitons to spin alignment of Mn2+ ions in Cd1xMnxTe A direct comparison of the splitting of free exciton states with the magnetic moment of the Mn 2+ ion system shows excellent agreement with simple exchange... JA Gaj,R Planel,G Fishman - ...
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 a negative susceptibility (net moment opposing the magnetic field)....
The frequency of this signal is near the Larmor frequency, and its initial amplitude, is determined by the magnitude of the transverse magnetic moment Mt. The amplitude, A, of the emitted NMR signal decays in an exponential fashion with time, t. The decay constant 1/T*2 depends on the ...
