Pressure-enhanced 3D antiferromagnetic correlations in La1.4Sr1.6Mn2O7. Kamenev, K., V., McIntyre, G., J., Arnold, Z., Kamarad, J., Lees, M., R., Balakrishnan, G., Chung, E., M., L., & Paul, D., M. Physical Review Letters, 87(16):art. no.-167203, 2001. Website abstract bibtex Pressure effects on the stability of magnetic phases in La1.4Sr1.6Mn2O7 have been studied using magnetization measurements and neutron diffraction. At ambient conditions this material is a quasi-two-dimensional ferromagnet. On cooling it becomes ordered three dimensionally: at 90 K La1.4Sr1.6Mn2O7 it becomes an antiferromagnet, and at 65 K it undergoes a transition into a ferromagnetic phase. Using neutron diffraction techniques on a single crystal of La1.4Sr1.6Mn2O7 it has been shown that these two magnetic phases belong to a single structural phase and do not coexist at low temperatures. The application of pressure enhances the antiferromagnetic correlations between the Mn2O9 bilayers.
