Influence of Mn site doping on electrical resistivity of polycrystalline La1-yAyMn1-xBxO3 (A=Ba, Sr; B=Cu, Cr, Co) Manganites [PDF]

Science of Sintering, 2008
We have the measured electrical resistivity of La1-yBayMn1-xCuxO3 (0.17≤y≤0.30; 0.04≤x≤0.10), La1-ySryMn1-xCrxO3 and La1-ySryMn1-xCoxO3 (0.270≤y≤0.294; 0.02≤x≤0.10) polycrystalline samples in the 25-325 K temperature range. The increase of Mn site doping

Colossal Magnetoresistance in Manganites as a Multicritical Phenomenon [PDF]

Physical Review Letters, 2003
The colossal magnetoresistance in manganites AMnO_3 is studied from the viewpoint of multicritical phenomena. To understand the complicated interplay of various phases, we study the Ginzburg-Landau theory in terms of both the mean-field approximation and the renormalization-group analysis to compare with the observed phase diagram.

Mixed orbital states and modulated crystal structures in La1−x Ca x MnO3 deduced from synchrotron X-ray diffraction

Communications Physics, 2023
In the model manganese perovskites La1−x Ca x MnO3, several important phenomena have been observed, including ferromagnetic metallic/insulating states, colossal magnetoresistance effects, and charge- and orbital-ordered states.

Influence of Thickness on the Magnetic and Magnetotransport Properties of Epitaxial La_0.7Sr_0.3MnO₃ Films Deposited on STO (0 0 1)

Nanomaterials, 2021
Epitaxial La0.7Sr0.3MnO3 films with different thicknesses (9–90 nm) were deposited on SrTiO3 (0 0 1) substrates by pulsed laser deposition. The films have been investigated with respect to morpho-structural, magnetic, and magneto-transport properties ...

Electrically Tunable, Rapid Spin-Orbit Torque Induced Modulation of Colossal Magnetoresistance in Mn3Si2Te6 Nanoflakes. [PDF]

Nano letters (Print)
As a quasi-layered ferrimagnetic material, Mn3Si2Te6 nanoflakes exhibit magnetoresistance behavior that is fundamentally different from their bulk crystal counterparts. They offer three key properties crucial for spintronics.

Colossal-magnetoresistive manganite thin films [PDF]

Journal of Physics: Condensed Matter, 2001
Mixed-valence perovskite manganites (Re$_{1-x}$A$_{x}$MnO$_{3}$ where Re=rare earth, A=alkaline earth) provide a unique opportunity to study the relationships between the structure and the magnetotransport properties due to an interplay among charge carriers, magnetic coupling, orbital ordering and structural distortion. This makes these compounds very

Colossal magnetoresistance in the insulating ferromagnetic double perovskites Tl2NiMnO6: A neutron diffraction study [PDF]

Acta Materialia, 2019
In the family of double perovskites, colossal magnetoresistance (CMR) has been so far observed only in half-metallic ferrimagnets such as the known case Sr2FeMoO6 where it has been assigned to the tunneling MR at grain boundaries due to the half-metallic
