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

The Pr 1-x Ca x MnO 3 (x≈ 0.5) manganites display an electronic localization together with
a modulated distortion of the structure below a transition temperature T CO. It is commonly …

The rich physics of colossal magnetoresistance compound is dominated by the intriguing
competition between ferromagnetic double exchange coupling and striped charge/orbital …

We introduce an effective model for eg electrons to describe three-dimensional perovskite
(La 1− x Sr x MnO 3 and La 1− x Ca x MnO 3) manganites and study the magnetic and …

Abstract Effects of chemical and external pressures have been investigated on the two types
of charge-ordering (CO) systems of perovskite manganites with the use of single-crystal …

The ground states of La 1-x Ca x MnO 3 change from double-exchange-associated
conducting ferromagnets at x< 0.50 to charge-ordered antiferromagnets at x> 0.50 even …

The highly Mn+ 4-doped compound La 0.35 Ca 0.65 MnO 3 has been studied up to high
temperature (700 K) by using thermal-expansion, magnetostriction, magnetoresistance, and …

We study a series of the perovskite manganite compounds La 1− x Ca x MnO 3 closely
spaced in doping near x= 0.50 where the ground state undergoes a doping-dependent …

The perovskite manganites Ln1xCaxMnO3 often exhibit, at low temperature, a charge
ordered state, 1–6 whose metastable character is crucial for the appearance of colossal …

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 …
