Spin-state crossover has long been subject to hot debate in doped and undoped perovskite oxide LaCoO3. The authors in this article have discovered that the crossover is enhanced by nonmagnetic Al3+ impurity doped into the Co-O network in the ferromagnetic La0.8Sr0.2CoO3. The introduced Al3+ ion changes the neighboring Co3+ ions from the intermediate-spin state to the nonmagnetic low-spin state at low temperatures, dramatically affecting the transport and magnetic properties in spite of its nonmagnetic nature.
