Abstract

We studied magnetic responses at low temperatures of Au/Co (tCo=0.7nm) /Au deposited on SiO2. By using Polar Magneto-Optical Kerr Effect (PMOKE) magnetometry, we determined the magnetization easy axis at 300 K. We used Superconducting QUantum Interference Device (SQUID) magnetometer, in polar configuration, to study the quasi-static parameters between 4-200K. Our results showed that the easy magnetization axis changes direction according to the temperature.
