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
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
