$\Delta$$\rho$/$\rho_0$ monotonically decreases as increasing the Pt thickness, which is different from the case of Pt/YIG, where the $\Delta$$\rho$/$\rho_0$ shows a maximum around t$_\textup{Pt}$ $\sim$ $\lambda_\textup{Pt}$ ($\lambda_\textup{Pt}$ is spin diffusion of Pt) [@Althammer2013]. For t$_\textup{Pt}$ $>$ 10 nm, there is no measurable oscillation for all three field scans.

Discussion
----------

Based on the above experimental data, we conclude that the observed extraordinary Hall resistance and unconventional magnetoresistance in Pt thin films are entangled with the ferromagnetism of LCO insulator. However, these spin transport properties can not be generally explained by the existing theory. The recent theoretical model, namely, SMR has been proposed to explain the observed UCMR in Pt/YIG hybrid, which is built on the spin Hall and inverse spin Hall effects and involves a conversion between the charge and spin current [@Nakayama2013; @Chen2013]. However, the SMR model is unable to describe the unusual temperature dependence of EHR whose magnitude and sign are highly non-trivial and the unsaturated UCMR at high fields [@Miao2014; @Huang2012]. There are at least three contributions to the observed EHR in Pt/LCO hybrids: magnetic proximity effect, spin Hall based SMR, and spin-dependent interface scattering. The Pt is near the stoner ferromagnetic instability and could become magnetic
