Magnetic hysteresis loops before (a, c, e, g) and after (b, d, f, h) paramagnetic correction; depth logs of low-field (i), paramagnetic (j), and ferrimagnetic susceptibilities (k); saturation magnetization (Ms) (l); and coercivity (Hc) (m) of selected samples from depths between 589.05 and 589.55 m in the WFSD-1 core.
After i.v. paramagnetic contrast administration, a rim of enhancement is usually visible in larger lesions and homogeneous enhancement is typically demonstrated in smaller tumours, as seen on CT scans.
Above the Curie point (also called the Curie temperature), the spontaneous magnetization of the ferromagnetic material vanishes and it becomes paramagnetic (i.e., it remains weakly magnetic).
In particular, for the detection of malignant lesions with hyperperfusion and intense enhancement, the i.v. administration of paramagnetic contrast material might be helpful and even increase detection rates.
Nevertheless, it is interesting to note that X has several spectral properties that are analogous to those of the P-cluster: (i) both clusters are paramagnetic with an integer spin in IDS; (ii) the spectra of both clusters in IDS are very broad, characteristic of large FeS clusters; and (iii) both clusters are diamagnetic in DTN.
Therefore, the amount of Al in the paramagnetic environments (i.e., Al with Fe3+ in its first cation coordination shell) can be estimated by subtracting the amount of diamagnetic Al, as estimated from the NMR, from the total amount of Al, as determined by elemental analysis.
These compounds are efficient 3D-ferrimagnets at low temperatures (Tc < 30 K) due to the presence of majority of FeII CN CoIII diamagnetic pairs which undergo upon irradiation photoinduced electron transfer resulting in <span class="lh">paramagnetic FeIII CN CoII species.
Paramagnetic Ni(I) complexes were investigated by cyclic voltammetry, spectroelectrochemistry UV/Vis and ESR methods at room temperature and in a frozen solution.

Three rounds of selection were carried out in solution using SAI/II antigen coupled to paramagnetic beads.
By tuning the Fe content, the magnetostructural transition from paramagnetic parent phase (i.e. austenite) with a Ni2In-type hexagonal structure to ferromagnetic TiNiSi-type martensite can be realized in a temperature window determined by the Curie temperature of the austenite and that of the martensite.
