Abstract
Magnetic pressure-temperature phase diagram of La1.4Sr1.6Mn2O7 layered manganite has been studied using magnetization measurements and neutron diffraction on single crystals. It has been found that La1.4Sr1.6Mn2O7 is a quasi two-dimensional ferromagnet at temperatures as high as 340 K. At lower temperatures it undergoes a series of phase transitions into magnetic phases with three-dimensional long-range order. At 90 K La1.4Sr1.6Mn2O7 becomes an antiferromagnet and at 65 K it undergoes a transition into a ferromagnetic phase. It has also been shown that applied pressure enhances the long-range antiferromagnetic correlations between Mn2O9 bilayers. These findings have been explained in terms of numerical calculations, taking into account pressure-induced electron transfer between 3d orbitals of the Mn ions.
