Magnetic anisotropy of ferromagnetic layered manganites

, 2003
The magnetic anisotropy of the ferromagnetic layered manganites La $_{2-2x}{\rm Sr}_{1+2x}{\rm Mn}_2{\rm O}_7$ is investigated. For x=0.4, the easy-plane anisotropy comes out predominantly from dipolar interaction but it is partly cancelled out by a ...

A note on the different crystalline features of the EuMnO₃-based solid solutions as a function of the modifying cation nature

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
The structural properties of solid solutions based on EuMnO3, in which Eu has been substituted by divalent Ca2+ and Mn by the divalent cation Ni2+ or the variable valence cation Co2+-Co3+ have been studied by X-ray diffraction (XRD) and X-ray absorption ...

Low field magnetotransport in manganites

, 2008
The perovskite manganites with generic formula RE1?xAExMnO3 (RE = rare earth, AE = Ca, Sr, Ba and Pb) have drawn considerable attention, especially following the discovery of colossal magnetoresistance (CMR).

Crystalline behaviour and electrical properties of manganese perovskites substituted on A or B sites: ErMnO₃ modified by Ca and EuMnO₃ modified by Co

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
The structural and electrical features of the manganites solid solutions (Er,Ca)MnO₃ and Eu(Co,Mn)O₃, have been studied by X-ray diffraction and conductivity measurements. Powders were prepared by solid-state

Comparison of electronic structures of orthorhombic and hexagonal manganites studied by X-ray absorption spectroscopy

, 2009
Electronic structures of orthorhombic perovskite-type manganites (OM) and hexagonal manganites (HM) are compared by using X-ray absorption near edge structure spectroscopy. This study reveals that the environments around Mn and O ions in both the systems

Large magnetic entropy change in Co-doped manganites

, 2005
Magnetic entropy change above 300 K, which is larger than that of gadolinium (Phys. Rev. B 57 (1998) 3478), has been observed in a Cu-doped manganites of La0.7Sr0.3Mn1−xCuxO3 (x=0.05,0.1).

Surface phase separation in nanosized charge-ordered manganites

, 2007
Recent experiments showed that the robust charge ordering in manganites can be weakened by reducing the grain size down to nanoscale. Weak ferromagnetism was evidenced in both nanoparticles and nanowires of charge-ordered manganites.

Magnetic, charge and orbital orderings in manganites

, 2001
We develop a theory to understand various types of electronic collective behaviors in manganites, such as magnetic, charge, and orbital orderings. Starting from an electronic model with strong correlations, we derive an effective Hamiltonian by utilizing
