Magnetoresistance studies of $L{a}_{2/3}S{r}_{1/3}Mn{O}_3$ - $YB{a}_{2}C{u}_3{O}_7$ - $L{a}_{2/3}S{r}_{1/3}Mn{O}_3$ trilayers with ferromagnetic coupling along the nodal direction of $YB{a}_{2}C{u}_3{O}_7$

Abstract

I have successfully prepared (110) trilayers of \LSMO-\YBCO-\LSMO. Magnetization measurements on these samples reveal a stronger coupling between the ferromagnetic layers. The coupling is an order of magnitude higher than that seen in the case of (001) trilayers. Magnetoresistance measurements show a first order transition in the data coinciding with the antiferromagnetic regime deduced from the magnetization measurements. I have also measured the anisotropic magnetoresistance (AMR) of these samples revealing an unusually high AMR ($\sim 72000$). I attribute such a high AMR to the pair breaking effects in these films.
