Evolution of the spin dynamics during freezing in the spin-glass FeCr
Steffen Säubert, Christian Franz, Johanna K. Jochum +5
In the iron--chromium system, FeCr, a wide dome of spin-glass behavior emerges when the ferromagnetism of iron is suppressed and the antiferromagnetism of chromium em…
Lattice dynamics reveals a local symmetry breaking in the emergent dipole phase of PbTe
Kirsten M. Ø. Jensen, Emil S. Božin, Christos D. Malliakas +5
Local symmetry breaking in complex materials is emerging as an important contributor to materials properties but is inherently difficult to study. Here we follow up an earlier stru…
Anomalous phonon behavior in the high temperature shape memory alloy: TiPd:Cr
S. M. Shapiro, G. Xu, B. L. Winn +3
Ti50 Pd50-xCrx is a high temperature shape memory alloy with a martensitic transformation temperature strongly dependent on the Cr composition. Prior to the transformation a premar…
Lattice dynamics of the high temperature shape memory alloy Nb-Ru
S. M. Shapiro, G. Xu, G. Gu +2
Nb-Ru is a high temperature shape memory alloy that undergoes a Martensitic transformation from a parent cubic b-phase into a tetragonal b' phase at TM 900 C. Measurements of the p…
Strain phase diagram and domain orientation in SrTiO thin films
Feizhou He, B. O. Wells, S. M. Shapiro
SrTiO thin films were used as a model system to study the effects of strain and epitaxial constraint on structural phase transitions of perovskite films. The basic phenomena re…
Defect Structure of the High-Dielectric-Constant Perovskite Cacu3ti4o12
L. Wu, Y. Zhu, S. Park +3
Using transmission electron microscopy (TEM) we studied CaCu3Ti4O12, an intriguing material that exhibits a huge dielectric response, up to kilohertz frequencies, over a wide range…
