An ultra-low field SQUID magnetometer for measuring antiferromagnetic and weakly remanent magnetic materials at low temperatures
Michael Paulsen, Julian Lindner, Bastian Klemke +4
A novel setup for the measurement of magnetic fields external to certain antiferromagnets and generally weakly remanent magnetic materials is presented. The setup features a highly…
Polarizing an antiferromagnet by optical engineering of the crystal field
Ankit S. Disa, Michael Fechner, Tobia F. Nova +5
Strain engineering is widely used to manipulate the electronic and magnetic properties of complex materials. An attractive route to control magnetism with strain is provided by the…
Observation of a charge-neutral muon-polaron complex in antiferromagnetic CrO
M. H. Dehn, J. K. Shenton, S. Holenstein +13
We report a comprehensive muon spin rotation (SR) study of the prototypical magnetoelectric antiferromagnet CrO. We find the positively charged muon () occupies sev…
Metastable ferroelectricity in optically strained
Tobia Nova, Ankit Disa, Michael Fechner +1
Fluctuating orders in solids are generally considered high-temperature precursors of broken symmetry phases. However, in some cases these fluctuations persist to zero temperature a…
Terahertz-Driven Phonon Upconversion in SrTiO3
Michael Kozina, Michael Fechner, Premysl Marsik +8
Direct manipulation of the atomic lattice using intense long-wavelength laser pulses has become a viable approach to create new states of matter in complex materials. Conventionall…
Ultrafast relaxation dynamics of the antiferrodistortive phase in Ca doped SrTiO3
M. Porer, M. Fechner, E. Bothschafter +19
The ultrafast dynamics of the octahedral rotation in Ca:SrTiO3 is studied by time resolved x-ray diffraction after photo excitation over the band gap. By monitoring the diffraction…
