Resistivity and ac-susceptibility measurements demonstrate that the cation size mismatch at
the A site in perovskite manganites influences greatly the electrical and magnetic properties …

Colossal magnetoresistance (CMR) effects have been observed in mixed-valent perovskite
manganites [1]. The mixed-valent manganites can be prepared by the partial substitution of …

To explore the optimized colossal magnetoresistance (MR), ie, higher MR with lower field,
magnetotransport properties of single-crystalline perovskite manganites have systematically …

We present a systematic study of the magnetotransport and magnetic properties of the half-
doped La 0.5 Ca 0.5 MnO 3+ δ system. The solid is a metamagnet which undergoes a first …

The magnetic and transport properties of a single crystal of Pr0. 7Ca0. 3MnO3 annealed by
various magnetic fields were investigated by dc and ac magnetization measurements. The …

The exploration of the magnetic and transport properties of four series of manganese
perovskites, Pr 0.7 Ca 0.34− x A x MnO 3− δ (A= Sr, Ba), Pr 0.7− x La x Ca 0.3 MnO 3− δ and …

Manganese perovskites have recently been the subject of renewed attention, due to the
“colossal” magnetoresistance (CMR) and the coupled metal-insulator and magnetic …

We report a synchrotron x-ray-scattering study of the magnetoresistive manganite La 0.875
Sr 0.125 MnO 3. At low temperatures, this material undergoes an x-ray-induced structural …

The influence of oxygen content on the magnetization and electrical resistivity of Ln 0.5 A 0.5
MnO 3 (Ln= La, Pr, Nd; A= Ca, Ba) manganites with the perovskite structure is investigated. It …

The colossal-magnetoresistance compound La 1− x Ca x MnO 3 shows a transition to
commensurate charge ordering (Mn 3+–Mn 4+) for x= 50%. In the range x= 42–50%, the …
