Evaluation of Born and local effective charges in unoriented materials from vibrational spectra
X. S. Xu, Q. -C. Sun, J. L. Musfeldt
We present an application of the Lorentz model in which fits to vibrational spectra or a Kramers Kronig analysis are employed along with several useful formalisms to quantify micro…
Linear and Nonlinear Optical constants of BiFeO_3
Amit Kumar, R. Rai, Nikolas Podraza +12
Using spectroscopic ellipsometry, the refractive index and absorption versus wavelength of the ferroelectric antiferromagnet Bismuth Ferrite, BiFeO_3 is reported. The material has…
Observation of 300 K High Energy MagnetoDielectric Response in the Bilayer Manganite (LaPr)SrMnO
J. Cao, R. C. Rai, S. Brown +8
We observed a large HEMD effect in the bilayer manganite (LaPr)SrMnO, a direct consequence of field driven spin-glass insulator to ferromagn…
In Search of Microscopic Evidence for Molecular Level Negative Thermal Expansion in Fullerenes
S. Brown, J. Cao, J. L. Musfeldt +5
We report the high-resolution far infrared vibrational properties of C60 and endohedral Kr@C60 fullerene as a function of temperature. Anomalous softening of the F1u(1) mode (526 c…
Dynamics of Bulk vs. Nanoscale WS_2: Local Strain and Charging Effects
R. D. Luttrell, S. Brown, J. Cao +3
We measured the infrared vibrational properties of bulk and nanoparticle WS in order to investigate the structure-property relations in these novel materials. In addition to th…
Observation of field-dependent magnetic parameters in the magnetic molecule {Ni4Mo12}
J. Schnack, M. Brueger, M. Luban +9
We investigate the bulk magnetic, electron paramagnetic resonance, and magneto-optical properties of {Ni4Mo12}, a magnetic molecule with antiferromagnetically coupled tetrahedral {…
