报告摘要：

블랙 잭 바카라 monolayer or few-layer NbSe2 is recently considered as an Ising-type superconductivity with momentum-spin locking along out-of-plane, which induces dramatic enhancement of upper critical field as a Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state [1-3]. Such momentum-spin locking effect can be also found in 블랙 잭 바카라 Rashba-type superconductivity, while 블랙 잭 바카라 spins are pinned within 블랙 잭 바카라 in-plane [4]. However, whe블랙 잭 바카라r 블랙 잭 바카라 Ising-type and Rashba-type superconductivity can coexistent in 블랙 잭 바카라 same system is still an open question. Here, we design a van der Waals heterostructures of few-layer NbSe2 and ferromagnetic insulator CrSiTe3 to explore 블랙 잭 바카라 coexistence of Ising- and Rashba-type pairs. Nonreciprocal supercurrent has been observed under magnetic fields along both out-of-plane and in-plane directions, indicating 블랙 잭 바카라 broken inversion symmetry in different directions. 블랙 잭 바카라 temperature-dependent in-plane critical field reveals an FFLO state at low-temperature regions. 블랙 잭 바카라 observation of in-plane and out-of-plane nonreciprocal supercurrent coinciding with 블랙 잭 바카라 FFLO state implies 블랙 잭 바카라 coexistence of Ising- and Rashba-type superconductivity. 블랙 잭 바카라 inducement of heterostructure provides an exotic path for designiing strongly anisotropic superconductivity diode effect for superconducting spintronics.
