Absence of charge-density-wave sliding in epitaxial charge-ordered Pr0.48Ca0.52MnO3 films
B. Fisher, J. Genossar, L. Patlagan +5
For an epitaxial Pr0.48Ca0.52MnO3 film on NdGaO3, we use transmission electron microscopy to observe a "charge-ordered" superlattice along the in-plane direction a. The same film s…
Determination of the Nature of the Tetragonal to Orthorhombic Phase Transition in SrFe_2As_2 by Measurement of the Local Order Parameter
J. C. Loudon, C. J. Bowell, J. Gillett +2
SrFe2As2 is the end-member for a series of iron-pnictide superconductors and has a tetragonal-to-orthorhombic phase transition near 200 K. Previous macroscopic measurements to dete…
Imaging Flux Vortices in Type II Superconductors with a Commercial Transmission Electron Microscope
J. C. Loudon, P. A. Midgley
Flux vortices in superconductors can be imaged using transmission electron microscopy because the electron beam is deflected by the magnetic flux associated with the vortices. This…
Limited local electron-lattice coupling in manganites
D. Sanchez, M. J. Calderon, J. Sanchez-Benitez +4
(Pr,Ca)MnO3 is the archetypal charge-ordered manganite, but in Pr0.48Ca0.52MnO3 we find (using convergent-beam electron diffraction and dark-field images) that the superlattice per…
Very weak electron-phonon coupling and strong strain coupling in manganites
S. Cox, J. C. Loudon, A. J. Williams +4
The coupling of the manganite stripe phase to the lattice and to strain has been investigated via transmission electron microscopy studies of polycrystalline and thin film manganit…
Strain control of superlattice implies weak charge-lattice coupling in LaCaMnO
S. Cox, E. Rosten, J. C. Chapman +6
We have recently argued that manganites do not possess stripes of charge order, implying that the electron-lattice coupling is weak [Phys Rev Lett \textbf{94} (2005) 097202]. Here…
