Strain induced phase separation on La0.5Ca0.5MnO3 thin films

Structural and electrical properties of LaNiO3 thin films grown on (100) and (001) oriented SrLaAlO4 substrates by chemical solution deposition method

“…Recently, Antonakos et al [37] reported La 0.5 Ca 0.5 MnO 3 films of various thickness grown on (0 0 1) oriented SrLaAlO 4 single crystal substrates by pulse laser deposition; The X-ray diffraction measurements showed that films epitaxial grown in (0 0 l) direction. In addition, Pervolaraki et al [38] reported La 5 Ca 9 Cu 24 O 41 films on (1 0 0) oriented SrLaAlO 4 single crystal substrates prepared by pulse laser deposition technique; The films exhibits mainly (0 k 0) preferred orientation although peak for polycrystalline samples, remains present.…”

Nature of temperature‐ and magnetic‐field‐dependent conduction mechanism in electron‐doped Ca0.85R0.15MnO3 (R = Pr, La) manganites

“…It has been observed that the conduction mechanism of the electron‐doped charge‐ordered Ca 0.85 La 0.15 MnO 3 system obeys the small‐polaron hopping model throughout the paramagnetic high‐temperature (160–300 K) and antiferromagnetic low‐temperature (90–150 K) phases . Many authors have also reported the structural properties and transport mechanism in this polycrystalline sample . However, much less is known about the conduction mechanism of such electron‐doped manganites (i.e., x < 0.2) up to 5 K and also with the application of high magnetic fields up to 15 T. Our plan in the present study is to concentrate on the conduction properties of electron‐doped CO‐antiferromagnetic insulating system Ca 0.85 R 0.15 MnO 3 (R = Pr, La) with and without an applied magnetic field.…”

Microstructural and magnetotransport properties of La1−xCaxMnO3 (0.45≤x≤0.60) thin films

“…Among the manganites, La 1 − x Ca x MnO 3 has been the most extensively studied compound [13][14][15][16][17][18][19][20][21][22][23][24]. The end members of the, viz.…”

“…However, there has been very little focus on the phase separation in thin films in the vicinity of half doping [11,20]. In the present work we focus on the coexistence of magnetic-electronic phases and hence phase separation in the range of 0.45 ≤ x ≤ 0.60 in high quality oriented polycrystalline thin films prepared by nebulized spray pyrolysis technique on single crystalline substrate LaAlO 3 [LAO (0 0 1)].…”
