Abstract: In dieser Arbeit werden epitaktische Dünnschichten aus nicht-kollinearen Antiferromagneten Mn3Ir und Mn3Sn mittels Magnetronsputtern hergestellt. Deren Kristallstruktur wird durch XRD und TEM charakterisiert. Messungen ihrer magnetischen Eigenschaften mittels VSM und XMCD zeigen die wichtige Rolle des nicht-kompensierten Mn-Moments. Um die Nützlichkeit der Dünnschichten für Spintronik einzuschätzen, wird der magnetische Transport in lithographisch hergestellten Bauelementen untersucht.
In this thesis, we prepare epitaxial thin films of the noncollinear antiferromagnets Mn3Ir and Mn3Sn, via magnetron sputtering. Their crystal structure is characterized by x-ray diffraction and transmission electron microscopy. Measurements of their magnetic properties, using vibrating sample magnetometry and x-ray magnetic circular dichroism, reveal the important role of uncompensated Mn moments. To assess the thin films' suitability for topological spintronic applications, we study magnetotransport in lithographically fabricated devices.
