of longitudinal ($\rho_\parallel$, $H \parallel$ $x$) and transverse ($\rho_\textup{T}$, $H \parallel$ $y$) MR for Pt (3 nm)/LCO/LAO hybrid measured at $T$ = 2 K are presented. Here the MR ratio is defined as MR = \[$\rho$($H$) - $\rho_0$\]/$\rho_0$. According to Eq. (1), the difference between longitudinal and transverse resistivity ($\Delta$$\rho$ = $\rho_\parallel$ - $\rho_\textup{T}$) depends on the relative angle between magnetization and current direction. So the $\Delta$$\rho$ should be a constant after LCO has been saturated for $\mu_0$H $>$ 30 KOe (see details in Fig. 2). However, the $\Delta$$\rho$ continuously increases as increasing the magnetic field, which is twice larger at 70 KOe (2.6 $\times$ 10$^{-4}$) than at 40 KOe (1.3 $\times$ 10$^{-4}$). Such unsaturated MR was also observed in Pt/YIG hybrid [@Miao2014], though it is believed to be caused by the MPE at Pt/YIG interface, but its nature is still far from understood. We also studied the angular dependence of MR for PLL hybrids with different Pt thickness. As shown in Fig. 11, where exhibits all $\theta_{xy}$, $\theta_{xz}$, and $\theta_{yz}$ scans at 10 K, the UCMR was observed in all hybrids with its magnitude $\Delta$$\rho$/$\rho_0$ reaching the maximum value of 1.2 $\times$ 10$^{-4}$. For all three scans, the magnitude
