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…
