Abstract

Systematic powder diffraction studies have been carried out to establish the magnetic phase diagram of La_2-2xSr_1-2xMn₂O₇ (LSMO327) in a wide hole concentration range (0.30 ≤ x ≤ 0.50), using the HERMES diffractometer. LSMO327 exhibits a planar ferromagnetic structure for 0.32 ≤ x ≤ 0.38 at low temperatures. A finite canting angle between planar magnetic moments on neighboring planes starts appearing around x approx. 0.40 and reaches 180° (A-type antiferromagnet) at x = 0.48. At x = 0.30, on the contrary, the magnetic moments are aligned parallel to the c-axis.
