| heal.abstract | Compositionally modulated structures consisting of La2/3Ca1/3MnO3 ferromagnetic (FM) layers and La1/3Ca2/3MnO3 antiferromagnetic (AF) layers, with layer thickness 1.5 nm less than or equal to t(FM),t(AF)less than or equal to 6 nm, were grown on (100)LaAlO3 by pulsed laser deposition. Thermomagnetic and isothermal magnetic measurements reveal an exchange-biasing mechanism with the same blocking temperature T(B)approximate to 70 K for all the examined combinations of t(FM) and t(AF). The ratio of colossal magnetoresistance increases in multilayers with larger t(FM), whereas the exchange-biasing field increases in samples with larger t(AF). The independence of T-B on t(FM) and t(AF) shows that the artificially induced La1-xCaxMnO3 (x approximate to 0.5) compositional modulation at the interfaces is of critical importance for exchange biasing in La-Ca-Mn-O based multilayers.
