Comparison of Hall resistance measured in two different types of contacts.
Hall resistance Rxy of a 30 uc LSTO/STO is measured at 2 K using two different contact methods. Silver contacts, which electrically contact only the LSTO, show linear Rxy. Wire bonds, which contact both LSTO and the interface of LSTO/STO, show nonlinear Rxy.
