Intrinsic Structural Disorder and the Magnetic Ground State in Bulk EuTiO3
A. P. Petrovic, Y. Kato, S. S. Sunku +8
The magnetic properties of single-crystal EuTiO3 are suggestive of nanoscale disorder below its cubic-tetragonal phase transition. We demonstrate that electric field cooling acts t…
On the role of intrinsic disorder in the structural phase transition of magnetoelectric EuTiO3
Mattia Allieta, Marco Scavini, Leszek Spalek +6
Up to now the crystallographic structure of the magnetoelectric perovskite EuTiO3 was considered to remain cubic down to low temperature. Here we present high resolution synchrotro…
Quantum criticality in ferroelectrics
S. E. Rowley, L. J. Spalek, R. P. Smith +4
Materials tuned to the neighbourhood of a zero temperature phase transition often show the emergence of novel quantum phenomena. Much of the effort to study these new effects, like…
Verwey transition in FeO at high pressure: quantum critical behavior at the onset of metallization
J. Spałek, A. Kozłowski, Z. Tarnawski +5
We provide evidence for the existence of a {\em quantum critical point} at the metallization of magnetite FeO at an applied pressure of GPa. We show t…
