This chapter presents a study of the magnetic properties and magnetic interaction mechanisms in a series of thiazyl radicals, which are of particular interest in the field of molecular magnetism. The chapter is organized as follows. First, there is an introduction to organic molecular magnetism and thiazyl radicals. The importance of an accurate knowledge of the spin density distribution in ord...

A quantum magnetic disk (QMD) a new paradigm for magnetic recording is proposed and fabricated. Tile QMD consists of pre-fabricated single-domain magnetic structures that have an identical shape and are uniformly embedded in a nonmagnetic disk. Each single-domain structure has a quantized magnetic moment and can store one bit of information. The QMD has a number of advantages over the conventio...

The temperature and magnetic field dependences of the critical current density in silicone oil-doped MgB2 polycrystalline samples have been investigated by magnetic measurements. The upper critical magnetic field anisotropy, γ = H⊥c c2 /H ||c c2 dependence of the critical current density, Jc(B), were analyzed within the percolation model. The calculated critical current densities based on perco...
