Observation of Kosterlitz-Thouless spin correlations in the colossally magnetoresistive layered manganite $L a_{1.2} S r_{1.8} M n_{2} O_{7}$

S. Rosenkranz, R. Osborn, L. Vasiliu-Doloc +3

The spin correlations of the bilayer manganite $L a_{1.2} S r_{1.8} M n_{2} O_{7}$ have been studied using neutron scattering. On cooling within the paramagnetic state, we observe purely…

Evidence for a Purely Double-Exchange Mechanism for the Anisotropic Conductivities in Layered La-Sr-Mn-O Single Crystals Below TC

Q. A. Li, K. E. Gray, J. F. Mitchell +2

Experimental evidence supports the double-exchange (DE) mechanism for both in-plane and c-axis conductivity in the colossal-magnetoresistive (CMR) layered manganite La1.4Sr1.6Mn2O7…
