Transport Properties of YBa2Cu3O7-x/CaMoO3 Multilayers in a Magnetic Field

The transport properties of superconducting YBa2Cu3O7-x/CaMoO3 (YBCO/CMO) multilayers in the mixed-state were measured to study the effects of magnetic field, flux pinning and current density on the behaviors of Hall coefficient. The superconducting critical temperature was reduced due to the presence of CM0 layers. The longitudinal resistivities under a magnetic field parallel to the c-axis shows a thermally activated behavior and pinning energy decreases with an increasing magnetic fields or currents applied. The pinning abilities are also affected by the thickness of YBCO or CMO layers. The negative Hall coefficient in the mixed-state depends on the flux pinning and decreases as the pinning force decreases. The results are consistent with the Wang and Ting's model [10].
