Linear and Circularly Polarized Light to Study Anisotropy and Resonant Scattering in Magnetic Thin Films
Helio C. N. Tolentino, Julio C. Cezar, Narcizo M. Souza-Neto +1
The remarkable polarization properties of the synchrotron light have lead to the advent of modern synchrotron-related spectroscopic studies with angular and/or magnetic selectivity…
Local tetragonal distortion in La_{0.7}Sr_{0.3}MnO_3 strained thin films probed by x-ray absorption spectroscopy
Narcizo M. Souza-Neto, Aline Y. Ramos, Hélio C. N. Tolentino +2
We report on an angular resolved X-ray Absorption Spectroscopy study of thin films epitaxially grown by pulsed laser deposition on slightly mismatched sub…
Phonon Activity and a Possible Lattice Arrangement in the Intermediate Phase of YVO3
Nestor E. Massa, Cinthia Piamonteze, Helio C. N. Tolentino +3
We show that in YVO3 new hard phonons gradually become zone center active below ~210 K verifying that a lattice phase transition takes place at about that temperature. The Debye-Wa…
Small Polaron Localization, Jahn-Teller Distortion and Defects in La0.67Ca0.33MnO3: An Infrared Spectroscopy and X-ray Absorption Analysis
Nestor E. Massa, Helio C. N. Tolentino, Horacio Salva +3
We combine infrared reflectivity and EXAFS (Extended X-ray Absorption Fine Structure) techniques to study the solid solution La0.67Ca0.33MnO3 prepared by different methods yielding…
