Systematic powder diffraction studies have been carried out to establish the magnetic phase diagram of La 2Ϫ2x Sr 1ϩ2x Mn 2 O 7 (LSMO327) in a wide hole concentration range (0.30 Յ x Յ 0.50), using the HERMES diffractometer. LSMO327 exhibits a planar ferromagnetic structure for 0.32 Յ x Յ 0.38 at lo
The specific heat ðCÞ of bi-layered manganites La 2 2 2x Sr 1 þ 2x Mn 2 O 7 (x ¼ 0:3 and 0.5) is investigated for the ground state of low temperature excitations. A T 3=2 dependent term in the low temperature specific heat (LTSH) is identified at zero magnetic field and suppressed by magnetic fields
