Abstract

Anisotropic charge dynamics has been investigated for single crystals of layered manganites, La2−2x Sr1+2x Mn2O7 (0.3≤x≤0.5). Remarkable variation in the magnetic structure as well as in the charge-transport properties is observed with changing doping-level x. A crystal with x=0.3 behaves like a 2-dimensional ferromagnetic metal at the temperature region between ~90 K and ~270 K, and shows the interplane tunneling magnetoresistance at lower temperatures which is sensitive to the interplane magnetic coupling between the adjacent MnO2 bilayers. Optical probe for these layered manganites has also clarified highly anisotropic and incoherent charge dynamics.
