In this paper, we refine and generalize some weighted arithmetic–geometric operator mean inequalities due to Lin (Stud. Math. 215:187–194, ) and Zhang (Banach J. Math. Anal. 9:166–172, ) as follows: Let A and B be positive operators. If 0 m ≤ A ≤ m′ M′ ≤ B ≤ M or 0 m ≤ B ≤ m′ M′ ≤ A ≤ M, then for a positive unital linear map Φ, where α ∈ [0, 1], , , , , r = min {α, 1 − α} and p ≥ 2.
