Discovery of intrinsic ferromagnetism in 2D van der Waals crystals
Cheng Gong, Lin Li, Zhenglu Li +12
It has been long hoped that the realization of long-range ferromagnetic order in two-dimensional (2D) van der Waals (vdW) crystals, combined with their rich electronic and optical…

Time-Reversal-Symmetry-Breaking Superconductivity in Epitaxial Bismuth/Nickel Bilayers
Xinxin Gong, Mehdi Kargarian, Alex Stern +6
Superconductivity that spontaneously breaks time-reversal symmetry (TRS) has been found, so far, only in a handful of 3D crystals with bulk inversion symmetry. Here we report an ob…

Direct observation of surface state thermal oscillation in SmB6 oscillators
Brian Casas, Alex Stern, Dmitry K. Efimkin +2
SmB6 is a mixed valence Kondo insulator that exhibits a sharp increase in resistance following an activated behavior that levels off and saturates below 4K. This behavior can be ex…
