Electron-doped Sm1−xSrxMnO3 perovskite manganites: Crystal and magnetic structures and physical properties

“…As already pointed out, all the Sm 1Àx Sr x MnO 3 manganites with 0.40pxp0.55 crystallize at room temperature in the orthorhombic space group Pbnm [4][5][6][7][8][9]. The discovery of another symmetry, tetragonal, in the compound with x ¼ 0.63 is in no way unexpected.…”

“…Depending on the actual concentration x of the element A, the physical properties of manganites can vary noticeably with a change in the temperature and external magnetic field, which, in turn, can induce sequences of phase transitions [1][2][3]. The present report is a continuation of our systematic physical investigation of the Sm 1Àx Sr x MnO 3 manganites [4][5][6][7][8][9], which are of considerable research interest [3,[10][11][12]. Owing to the large difference between the ionic radii of samarium and strontium the Sm 1Àx Sr x MnO 3 manganites exhibit, with a rather typical behavior for manganites, unique physical properties with a vivid manifestation of interactions between the electron, phonon, and magnetic subsystems.…”

Electronic, structural and magnetic phase diagram of Sm1-xSrxMnO3 manganites

“…62 in the International Tables for Crystallography) [1][2][3][4][5][6][7]. However, the relation between the unit cell parameters is varied with x.…”

“…There were no detailed data on the crystal and magnetic structures of the Sm-Sr system, which are necessary to explain all physical phenomena in these compounds. In this work, we present the electronic, structural and magnetic phase diagram of perovskite manganites Sm 1 À x Sr x MnO 3 (0.16 rxr0.67) constructed using the results of our long-term systematic studies of this system by highresolution neutron powder diffraction on samples synthesized using 152 Sm and 154 Sm isotopes reported previously [1][2][3][4][5][6][7][8][9][10] as well as new unreported data.…”

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

“…Sm 1 − x Sr x MnO 3 is one of the manganites which exhibits the colossal magnetoresistive property. Many researches are devoted to study this interesting topic and scientists are willing to improve the characteristic of such compounds [9][10][11][12][13][14][15][16].…”
