Crystals are a state of matter characterized by periodic order. Yet, crystalline materials can
harbour disorder in many guises, such as non-repeating variations in composition, atom …

The charge ordering (CO) and magnetic properties of La 0.25 Ca 0.75 Mn O 3 compounds
with average particle sizes ranging from 40 to 2000 nm have been studied. With decreasing …

A detailed study of the properties of the ferromagnetic to paramagnetic transition in
polycrystalline manganites La 1− x Ca x MnO 3 (x= 0.2, 0.3, 0.4) is presented. The first order …

The grain-size effects on the charge ordering and exchange bias in CE-type
antiferromagnetic charge ordered manganite compound Pr 0.5 Ca 0.5 MnO 3 are explored …

We review colossal magnetoresistance in single phase manganites, as related to the field
sensitive spin-charge interactions and phase separation; the rectifying property and …

We study the effects of disorder on a system of two coupled chains of strongly correlated
fermions (the ladder system), using a renormalization-group technique. The stability of the …

X-band electron magnetic resonance together with dc and ac magnetic measurements were
employed for comparative study of magnetic ordering in bulk and nanometer-sized La 0.9 …

The detailed evolution of the magnitude of the local Jahn-Teller (JT) distortion in La1
xCaxMnO3 is obtained across the phase diagram for 0 x 0: 5 from high-quality neutron …

Coexistence of charge-ordered (CO) and monoclinic (M) phases has been investigated in
La 1− x Ca x Mn O 3 (x= 0.6, 0.67, and 0.7). For this purpose, pellets and their corresponding …

The La 1− x Ca x MnO 3 series of compounds with antiferromagnetic ground states (x≥ 1/2)
have been extensively studied due to the novel spin, orbital, and charge-ordering states …
