Abstract: A room temperature Magneto Optical Kerr Effect (MOKE) experimental setup was expanded to improve performance and integrated with a liquid Helium cryogenic system. Ferromagnetic/superconductor hybrid systems have recently been intensively studied due to their interesting proximity effect and the possible applications such as a current switching device. Most of previous work focused on the superconducting property change due to the presence of the ferromagnet but not much research of the magnetic property change due to the superconducting transition has been done. Using the extended MOKE setup, magnetization from the top ferromagnetic layer can be measured below and above the critical temperature of the superconducting thin film layer. Temperatures as low as 4.2K were achieved and the magnetization with respect to applied magnetic field of a Permalloy/Niobium (Py/Nb) thin film was measured at 295K, 11K, and 4.2K. Coercivity increased as temperature decreased. A magnetization measurement with constant applied magnetic field was also performed with a temperature sweep passing the superconducting transition. However, due to temperature instability it was difficult to compare the magnetization above and below Tc of the Nb. Both hysteresis loops above and below the superconducting critical temperature were measured to be similar within the measurement error and have a coercivity of 160 ±16 Oe. Reasons for not detecting a magnetization change due to the superconductor could be either due to sample heating, thermometer calibration, the limited accuracy of measuring the coercivity in this sample, or the change due to the SC may be smaller or not exist.

Magnetische Materialien spielen in der heutigen Technik eine große Rolle. Seit der Entdeckung des Magnetismus sind viele Untersuchungsmethoden entwickelt worden. Wir haben eine Messapparatur zur Bestimmung von Magnetisierungskurven bei tiefen Temperaturen aufgebaut. Die Messungen können in einem Temperaturbereich von 10K bis 300K bei einem maximalen Magnetfeld von 0.8T durchgeführt werden. Um unsere Messapparatur zu testen haben wir die magnetischen Oxide Fe3O4 und SrRuO3 benutzt. Um das Auflösungsvermögen unseres Versuchsaufbaus zu erhöhen, haben wir die erste Variante von einer Ein-Detektor Methode mit Lock-In Verstärker zu einer Zwei-Detektor Differenzmethode umgebaut. Das maximale Auflösungsvermögen liegt bei 2mdeg. Weitere Untersuchungen wurden an SrRuO3 und La(0,67)Sr(0,33)MnO3 Dünnschichten durchgeführt. Es war dabei von besonderem Interesse die magnetischen Anisotripieeigenschaften zu bestimmen. Außerdem wurde das Wachstum von NiFe2O4 Dünnschichten untersucht. Zwei Serien wurden mittels einer RF-Sputter Anlage hergestellt. Hauptaugenmerk lag dabei auf der Analyse der Oberflächenstruktur.
