The theoretical calculations revealed multiple bands with a high density of Fe d states at the Fermi level, suggesting an itinerant character of the magnetism. The associated sheet-like structures of the Fermi surface provide nest- ing instabilities and thus promote the AFM ground state2. Based ...
Figure 2. Parametrized single antenna design configuration. Technologies 2023, 11, 142 6 of 20 The initial single antenna underwent a series of four iterative optimization stages to achieve the desired performance outcomes, as depicted in Figure 1a–d. In iteration 1, the antenna is designed with...
