Dynamics of Proximate Order Parameters Measured by the Time-Resolved Magneto-Optical Kerr Effect in SrRuO$_{3}$ /YBa$_{2}$Cu$_{3}$O$_{7-x }$Heterostructures

Abstract

The interaction between ferromagnetic and superconducting complex oxides in a heterostructure is a subject of great interest. The recent observation of ferromagnetic resonance in SrRuO$_{3}$ by the time-resolved magneto-optical Kerr effect (TRMOKE) presents a new method for insight into such a system. TRMOKE has been used to compare the temperature dependence of magnetization dynamics in SrRuO$_{3}$ grown on insulating substrates and ferromagnetic SrRuO$_{3}$/superconducting YBa$_{2}$Cu$_{3}$O$_{7-x }$heterostructures. The substantial differences between SRO grown on an insulating substrate compared to YBCO as well as the effects seen upon passing through the YBCO transition temperature are reported.
