Two Component Heat Diffusion Observed in CMR Manganites
J. Bielecki, R. Rauer, E. Zanghellini +3
We investigate the low-temperature electron, lattice, and spin dynamics of LaMnO_3 (LMO) and La_0.7Ca_0.3MnO_3 (LCMO) by resonant pump-probe reflectance spectroscopy. Probing the h…
Using neutron spin-echo to investigate proton dynamics in proton-conducting perovskites
Maths Karlsson, Dennis Engberg, Mårten E. Björketun +9
We demonstrate the applicability of studying the proton dynamics in proton-conducting perovskites using neutron spin-echo spectroscopy, a powerful method hitherto neglected for stu…
Anharmonic softening of Raman active phonons in Iron-Pnictides; estimating the Fe isotope effect due to anharmonic expansion
M. Granath, J. Bielecki, J. Holmlund +1
We present Raman measurements on the iron-pnictide superconductors CeFeAsO_{1-x}F_{x} and NdFeAsO{1-x}F_{x}. Modeling the Fe-As plane in terms of harmonic and a cubic anharmonic Fe…
Two-magnon Raman scattering from the Cu3O4 layers in (Sr,Ba)2Cu3O4Cl2
J. Holmlund, C. S. Knee, J. Andreasson +3
(Sr,Ba)CuOCl are antiferromagnetic insulators which are akin to the parent compounds of the cuprate superconductors but with two distinct magnetic ord…
