A Family of Lanthanide Noncentrosymmetric Superconductors La${}_4$$TX$ ($T$ = Ru, Rh, Ir; $X$ = Al, In)

Hang Su, Feng Du, Shuaishuai Luo +10

We report the discovery of superconductivity in a series of noncentrosymmetric compounds La${}_4$$TX$ ($T$ = Ru, Rh, Ir; $X$ = Al, In), which have a cubic crystal structure with spac…
