Creating 바카라 배팅 법 superconductivity in artificial metallic heterostruct…

" Superfluidity does not necessarily require a spin singlet state for a pair of fermions as the ground state, although the BCS theory of superconductivity assumes singlet pairing.For example, in 3He superfluid, a spin 바카라 배팅 법 state was found to be possible. In solid state materials, there have been reports of 바카라 배팅 법 superconductivity in some heavy fermion materials and, recently, in Sr2RuO4. Here we report on Tc behavior of Nb/Au(Al)/CoFetrilayers with respect to d_Au(Al) and d_CoFe, respectively. We show our results cannot be explained by the current theories based on singlet superconductivity and, instead, support the existence of 바카라 배팅 법 superconductivity in these artificial metallic heterostructures. Spin 바카라 배팅 법 states in artificial structures could pave a way to studying this interesting phenomenon in a systematic and controlled fashion. "
