Spin-lattice coupling induced weak dynamical magnetism in EuTiO3 at high temperatures
EuTiO3, which is a G-type antiferromagnet below TN = 5.5 K, has some fascinating properties at high temperatures, suggesting that macroscopically hidden dynamically fluctuating weak magnetism exists at high temperatures. This conjecture is substantiated by magnetic field dependent magnetization measurements, which exhibit pronounced anomalies below 200 K becoming more distinctive with increasin...
متن کاملFirst-principles prediction of oxygen octahedral rotations in perovskite-structure EuTiO3
We present a systematic first-principles study of the structural and vibrational properties of perovskite-structure EuTiO3. Our calculated phonon spectrum of the high-symmetry cubic structural prototype shows strong Mand R-point instabilities, indicating a tendency to symmetry-lowering structural deformations composed of rotations and tilts of the oxygen octahedra. Subsequent explicit study of ...
متن کاملTuning the structural instability of SrTiO3 by Eu doping: the phase diagram of Sr1-xEuxTiO3
Recently we have shown that the almost multiferroic system EuTiO3 undergoes a structural phase transition at TS=282K from cubic to tetragonal [1]. This transition is analogous to the one of SrTiO3 at TS=105K, where the oxygen octahedral rotations freeze out due to the softening of a transverse acoustic zone boundary mode. Besides of this similarity between SrTiO3 and EuTiO3, also others exist, ...
متن کاملObservation of a sample-dependent 37K anomaly on the lattice parameters of strontium titanate
– The lattice parameters of tetragonal strontium titanate are determined to about 1 part in 10 with penetrating X-rays. While no peculiarity is detected in a bulk sample, a distinct anomaly at 37K is observed in an optically polished thin platelet derived from the same single crystal. This suggests that the anomaly is related to a high density of dislocations. A possible mechanism is that dislo...
متن کاملSe p 19 96 Instabilities in the Flux Line Lattice of Anisotropic Superconductors
The stability of the flux line lattice has been investigated within anisotropic London theory. This is the first full-scale investigation of instabilities in the 'chain' state, the equilibrium lattice that is similar to the Abrikosov lattice at large fields but crosses over smoothly to a pinstripe structure at low fields. By calculating the normal modes of the elasticity matrix, it has been fou...
