Instead, we shall consider an interaction between spins through conduction electrons; i.e., RKKY) interaction. Although the Kondo effect screens the impurity spin and makes the system nonmagnetic, RKKY makes the magnetic moment stabilized. The studies of the two impurity spin system showed that mod...
5a. Thereafter, an RC structure with only one physical node (Single Node RC)41 but with far more virtual nodes from sampling the states of the physical node of the different moment has been proposed and proven to show great potentials in physically implementing RC on platforms like spin ...
The orbital and spin contributions to the magnetic moment of Fe in Fe3O4 nanoparticles were measured using X-ray magnetic circular dichroism (XMCD). Nanoparticles of different sizes, ranging from 5 to 11 nm, were fabricated via organic methods and their magnetic behavior was characterized by ...
摘要: Spin–rotation coupling, or Mashhoon effect, is a phenomenon associated with rotating observers. We show that the effect plays a fundamental role in the determination of the anomalous magnetic moment of the muon, is sizable and violates the principle of equivalence.关键词:...
Several realistic spin-orbital models for transition metal oxides go beyond the classical expectations and could be understood only by employing the quantum entanglement. Experiments on these materials confirm that spin-orbital entanglement has measurabl
Although many A3B2B’O9 compounds have been studied recently, La3Ni2TaO9 [6] is the only one for which the magnetometry and out–of–field neutron diffraction data mimic those collected from La3Ni2SbO9. Indeed, on careful inspection of the data, no magnetic scattering could be detected at...
The exchange-coupled [Co/Ni]N/TbFe nano-magnetic films can display strong perpendicular magnetic anisotropy (PMA) which depends on the Tb:Fe component ratio, TbFe layer thickness and the repetition number N of [Co/Ni]N multilayer. Perpendicular spin valves in the nano thickness scale, consisting...
The need for efficient ammonia synthesis is as urgent as ever. Over the past two decades, many attempts to find new catalysts for ammonia synthesis at mild conditions have been reported and, in particular, many new promoters of the catalytic rate have be
