Magneto-optical evidence for single-crystal-like magnetic switching of epitaxial antiferromagnetic LaFeO3 films
A. Rieche, W. Hoppe, C. Körner +11
Strained epitaxial films of the antiferromagnetic orthoferrite LaFeO3 offer a promising platform for antiferromagnetic spintronics, yet their magnetic switching behavior and domain…
Conductive domain walls in ferroelectrics as tunable coherent THz radiation source
Ramaz Khomeriki, Kathrin Dörr, Jamal Berakdar
THz emission associated with currents in conductive domains in BiFeO following infrared radiation is theoretically investigated. This experimentally observed phenomenon is expl…
Efficient broadband terahertz generation by above band-gap excitation of the pyroelectric ZnSnN2
T. S. Seifert, H. Hempel, O. Gückstock +10
Terahertz (THz) radiation is a powerful probe of low-energy excitations in all phases of matter. However, it remains a challenge to find materials that efficiently generate THz rad…
Ultrafast electron dynamics upon above band-gap excitation in epitaxial LaFeO(001) thin films
Friederike Elisa Wührl, Antonia Rieche, Anne Oelschläger +2
Strong electron correlations in perovskite oxides give rise to rich and often unexpected electronic phenomena. In this study, we present a comprehensive surface-science investigati…
Polarization rotation in a ferroelectric BaTiO film through low-energy He-implantation
Andreas Herklotz, Robert Roth, Zhi Xiang Chong +6
Domain engineering in ferroelectric thin films is crucial for next-generation microelectronic and photonic technologies. Here, a method is demonstrated to precisely control domain…
Growth-sequence-dependent interface magnetism of SrIrO - LaSrMnO bilayers
L. Bergmann, P. Düring, S. Agrestini +9
Bilayers of the oxide 3d ferromagnet LaSrMnO (LSMO) and the 5d paramagnet SrIrO (SIO) with large spin-orbit coupling (SOC) have been investigated regard…
Mn/Mn state of LaCeMnO by oxygen reduction and photodoping
Andreas Thiessen, Elke Beyreuther, Stefan Grafström +5
Films of cerium-doped LaMnO, which has been intensively discussed as an electron-doped counterpart to hole-doped mixed-valence lanthanum manganites during the past decade, were…
Influence of strain on magnetization and magnetoelectric effect in La0.7A0.3MnO3 / PMN-PT(001) (A = Sr; Ca)
C. Thiele, K. Dorr, O. Bilani +2
We investigate the influence of a well-defined reversible biaxial strain <=0.12 % on the magnetization (M) of epitaxial ferromagnetic manganite films. M has been recorded depending…
Structure, Tranport and Magnetism of La(0.67)Ca(0.33)Mn(1-x)Ta(x)O(3)
L. Seetha Lakshmi, K. Doerr, K. Nenkov +3
For the first time,we report the effect of pentavalent subtitution at the Mn site of La(0.67)Ca(0.33)MnO(3). The ferromagnetic -metallic ground state modifies to a cluster-glass in…
