We have used laser deposition to make YBa2Cu3O7−&dgr;/NdGaO3/YBa2Cu3O7−&dgr;trilayer structures. NdGaO3films grow epitaxially on well lattice‐matched substrates, like SrTiO3(100), and onc‐axis oriented YBa2Cu3O7−&dgr;films. Epitaxial YBa2Cu3O7−&dgr;films were grown on top of the NdGaO3films, and there was no significant difference in critical temperature between top and bottom layers of the trilayer structures. The resistivity of a 300‐nm‐thick NdGaO3interlayer was as high as 108&OHgr; cm at 300 K.
