アブストラクト We have investigated the effects of growth interval in pulsed laser deposition on structural, magnetic, and electrical transport properties of (111)-oriented Sr2CrReO6 double perovskite films. It was found that the degree of B-site ordering varied in a wide range by just changing the growth interval. Magnetization under 1 T and metallicity (the ratio of room-temperature resistivity to minimum resistivity at low temperatures) monotonically increased with increasing degree of ordering and reached values nearly identical to bulk. This technique, called pulsed laser interval deposition, may provide more efficient way to study relations between structural and physical properties in double perovskites than controlling growth parameters, such as temperature and oxygen partial pressure.
