Notes:
We have grown c-axis oriented films of a layered perovskite La2−2xSr1+2xMn2O7 (x=0.4) by pulsed laser deposition under the limited growth condition; above 900 °C and below 100 mTorr for substrate temperature and oxygen pressure (PO2), respectively. Otherwise, epitaxial but composition-unidentified films were deposited. The films show a resistive transition around 100 K in coincidence with the magnetic transition. The value of resistivity at low temperature is larger than that of a single crystal by about two orders of magnitude, perhaps due to the canted spin ordering. The films show gigantic magnetoresistance accompanied with hysteresis. © 1998 American Institute of Physics.
