Colossal magnetoresistance manganites

Uspekhi Fizicheskih Nauk, 2017
We review lattice, thermodynamic, transport, high-frequency, and optical properties of Re1 − x Dx MnO3 manganites, where Re is a rare earth and D is usually an alkaline-earth element. Colossal magnetoresistance (CMR) is the most famous effect observed in

Colossal Magnetoresistance in New Manganites

MRS Proceedings, 1999
AbstractThe evolution of structural, electrical and magnetic properties with the isovalent chemical substitution of Ca2+ into the Sr2+ sites in new series of two-dimensional La1.2(Srl.8−XCax)Mn2O7 compounds (x = 0 ∼ 1.8) and three-dimensional La0.6(Sr0.4−xCax)MnO3 compounds (x = 0 ∼ 0.4) are investigated. The highest magnetoresistance (MR) ratios [ρ(0)

Colossal magnetoresistance in La-Ca-Mn-O

Metals and Materials, 1997
ABSTRACTVery large increase in electrical conductivity by several orders of magnitude is obtained when an external magnetic field is applied to the colossal magnetoresistance (CMR) materials such as La-Ca-Mn-O. The magnetoresistance is strongly temperature-dependent, and exhibits a sharp peak below room temperature, which can be shifted by adjusting ...

Physica B: Condensed Matter, 2000
Abstract Structural, magnetic and transport properties of the polycrystalline manganese perovskite La 0.96−y Nd y K 0.04 MnO 3+δ with 0⩽y⩽0.4 have been experimentally studied. A partially disordered state is created as La is substituted by Nd, reflecting the competition between the ferromagnetic double-exchange and ...

Colossal magnetoresistive manganites

Journal of Magnetism and Magnetic Materials, 1999
Abstract Magnetoelectronic features of the perovskite-type manganites are overviewed in the light of the mechanism of the colossal magnetoresistance (CMR). The essential ingredient of the CMR physics is not only the double-exchange interaction but also other competing interactions, such as ferromagnetic/antiferromagnetic superexchange interactions ...
