Early theoretical attempts at investigating the electronic properties of such a material found that a periodic arrangement of B or N dopants, forming a dopant superlattice, would open a band gap [16], but that a random distribution of dopants among

Further DFT studies showed that the band gap will increase with dopant concentration [36][47] and that a dopant level

The hysteresis characteristics of interacting elliptical nanomagnets are described by a quasi-static method that identifies the critical boundaries

To a reasonable degree of accuracy, given the high accuracy of modern fabrication technologies, each of the N magnetic layers in the superlattice can be taken as having the same demagnetization factors.

The underlying assumption is that for very small grain sizes plasticity can be carried by grain boundary (GB) mediated processes rather than by energetically expensive superlattice

The presence of superlattice planes along the [001] axis proves the presence of L10 phase. Moreover, the particle in Figure 8(a) appears nearly spherical exhibiting no obvious defects
