The influence of tilt angle on the CMR in Sm0.6Sr0.4MnO3

Ultrasonic and elastic moduli evidence for Curie temperature (Tc) in Sm1−xSrxMnO3 perovskite magnetic materials at x=0.25, 0.30, 0.37, 0.40 and 0.44

“…A decrease in velocity up to 175 K followed by a sharp increase in velocity with a maximum at 165 K with decrease in temperature is observed in B region. In C region, an initial increase in velocity up to 148 K followed by a decrease Ultrasonic studies have been made on SSMO materials and observed results are compared with results obtained from other studies of SSMO perovskite manganite materials [19,20]. This helps to understand physical properties exhibited by SSMO materials.…”

Coexistence of superconductivity and ferromagnetism in La1.85Sr0.15CuO4–La2/3Sr1/3MnO3 matrix composites

“…The similar structural and transport properties of the manganite and cuprate powders have stimulated many attempt of building hybrid composite [19][20][21][22]. La 2/3 Sr 1/3 MnO 3 was chosen in this study due to the fact that it is a typical double exchange ferromagnetic compound with a high Curie temperature (T Curie = 370 K) owning to its very large one-electron bandwidth [23][24][25][26][27]. In order to clarify the interaction between superconductivity and magnetism, in this work, we successfully prepared a series of matrix composites with a stoichiometric formula of (La 1 the ferromagnetism in the microscale does not destroy superconductivity for LSCO cuprate in this kind of the matrix composites.…”

Electrical transport and magnetic properties in La0.7Sr0.3MnO3 and SrFe12O19 composite system

“…Perovskite manganites Ln 1−x A x MnO 3 (Ln: trivalent rare-earth ions and A: divalent alkaline-earth ions) have attracted lots of interests due to their fascinating negative colossal magnetoresistance (CMR) effect and technological applications for various functional devices [1][2][3][4][5][6]. La 0.7 Sr 0.3 MnO 3 (LSMO) possesses the highest value of Curie temperature (T C = 370 K) and combines low carrier density (10 21 to 10 22 cm −3 ) with a high spin polarization of charge carriers among CMR materials, which makes it very promising in room temperature applications [7,8].…”
