In this article, we prove the following results. Let L(F(ni)) be the free group factor on nigenerators (ni⩾2) and λ(gi) be one of standard generators of L(F(ni)) for 1⩽i⩽N. Let Aibe the abelian von Neumann subalgebra of L(F(ni)) generated by λ(gi). Then the abelian von Neumann subalgebra ⊗i=1NAiis a maximal injective von Neumann subalgebra of ⊗i=1NL(F(ni)). When N is equal to infinity, we obtain strongly stable II1factors (or called McDuff factors) that contain maximal injective abelian von Neumann subalgebras.
