We measured the transport properties of a-axis oriented YBa2Cu3Oy/La0.7Ca0.
3MnOy (YBCO/LCMO) muitilayers to study the effects of layer coupling on the
superconductivity, magnetoresistance and anomalous Hall effects. The decre
ase of flux pinning in the YBCO/LCMO multilayer causes the diminishing of s
ign reversal of Hall coefficients, The normal state magnetoresistance was f
ound to depend on the coupling strength of ferromagnetic layers.
