The synthesis of mononuclear molecular complexes, in which a single ion is wrapped by a shell of organic ligands, provides an alternative method for creating arrays of nearly isolated lanthanide spin qubits. The study of these materials was boosted by Ishikawa and coworkers [94] discovery of magnetic hysteresis in...

Figure 10 Comparison of partial magnetization hysteresis loops at 30 and 77 K for a superconducting T Ca j Ba2Cu20o single crystal (Tc is 105 K). The lack of hysteresis at 77 K is due to weak flux pinning.

The thus obtained high-density Mn-Zn ferrite was investigated in detail from the view of physical and mechanical properties, that is, the relationships between the composition of metals (a,) ) and <5 the magnetic properties such as temperature and frequency dependence of initial permeability, magnetic hysteresis loss and disaccommodation and the mechanical properties such as modulus of elasticity, hardness, strength, and workability. Figures 3.13(a) and (b) show the optical micrographs of the samples prepared by the processes depicted in Fig. 3.12(a) and (b), respectively. The density of the sample shown in Fig. 3.13(a) reached up to 99.8 per cent of the theoretical value, whereas the sample shown in Fig. 3.13(b) which was prepared without a densification process, has many voids.
