Abstract

We report on the growth of bulk samples (composite fibers) of the nominal composition La0.7Ce0.3MnO3 (LCMO) manganites (with Curie temperature T C,max = 300 K) by using the laser heated pedestal growth (LHPG) technique. Samples composition was verified through scanning electron microscopy with energy dispersive X‐ray (EDX) analysis. The magnetic behavior of the fibers was probed by magnetization measurements. In addition to a weak ferromagnetic transition at T C0 = 45 K (due to MnO2 impurities), two more transitions with T C1 = 126 K and T C2 = 180 K were identified and linked to regions with cerium concentration of x  = 0.063 and 0.13, respectively.
