Hybrid antiferroelectric-ferroelectric domain walls in noncollinear antipolar oxides
Ivan N. Ushakov, Mats Topstad, Muhammad Z. Khalid +15
Antiferroelectrics are emerging as advanced functional materials and are fertile ground for unusual electric effects. For example, they enhance the recoverable energy density in en…
Cascaded Raman lasing in a lithium tetraborate (LB4) whispering gallery mode resonator
Chengcai Tian, Florian Sedlmeir, Jervee Punzalan +5
Lithium tetraborate (LB4) is a lithium borate compound and recently has shown renewed interest due to its exceptional linear and nonlinear optical properties. Its wide transparency…
Crystal structure and absence of magnetic order in single crystalline RuO
Lara Kiefer, Felix Wirth, Alexandre Bertin +7
RuO was considered for a long time to be a paramagnetic metal with an ideal rutile-type structure down to low temperatures, but recent studies on single-crystals claimed eviden…
Spin-orbital-lattice entanglement in the ideal j=1/2 compound KIrCl
P. Warzanowski, M. Magnaterra, Ch. J. Sahle +9
Mott insulators with spin-orbit entangled j=1/2 moments host intriguing magnetic properties. The j=1/2 wave function requires cubic symmetry, while a noncubic crystal field mixes j…
Spin-orbit coupling in a half-filled shell: the case of KReCl
P. Warzanowski, M. Magnaterra, G. Schlicht +9
The half-filled shell of the configuration usually, in LS coupling, hosts a S = 3/2 ground state with quenched orbital moment. This state is not Jahn-Teller act…
Single-crystal study of the honeycomb XXZ magnet BaCo(PO) in magnetic fields
Xiao Wang, Rohit Sharma, Petra Becker +2
We present a study of high-quality BaCo(PO) single crystals via magnetization, heat-capacity, thermal-expansion and magnetostriction measurements. Sharp anomalies in th…
Low-temperature ordered phases of the spin- XXZ chain system CsCoCl
O. Breunig, M. Garst, A. Rosch +6
In this study the magnetic order of the spin-1/2 XXZ chain system CsCoCl in a temperature range from 50 mK to 0.5 K and in applied magnetic fields up to 3.5 T is investigat…
Infrared-active phonon modes in monoclinic multiferroic MnWO4
T. Möller, P. Becker, L. Bohaty +2
We report on polarized infrared reflectivity measurements of multiferroic, monoclinic MnWO4 between 10K and 295K. The full dielectric tensor and the frequency dependence of the ori…
