In this paper, we consider the following nonlinear Schrödinger equation with attractive inverse-power potentials

i t ψ + Δ ψ + γ | x | σ ψ + | ψ | α ψ = 0 , ( t , x ) R × R N ,

where N 3, 0 < γ < , 0 < σ < 2 and 4 N < α < 4 N 2 . By using the concentration compactness principle and considering a local minimization problem, we prove that there exists a γ 0 > 0 sufficiently small such that 0 < γ < γ 0 and for any a ( 0 , a 0 ), there exist stable standing waves for the problem in the L 2 -supercritical case. Our results are complement to the result of Li-Zhao in [23].
