Origin of colossal magnetoresistance in LaMnO 3 manganite [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2015 Significance Magnetoresistance is the change of resistance in the presence of an external magnetic field. In rare-earth manganite compounds, this change is orders of magnitude stronger than usual and it is promising for developing new spintronic and electronic devices. The colossal magnetoresistance (CMR) effect has been observed

Colossal magnetocapacitance and colossal magnetoresistance in HgCr2S4 [PDF]
Physical review letters, 2006 We present a detailed study of the dielectric and charge transport properties of the antiferromagnetic cubic spinel HgCr2S4. Similar to the findings in ferromagnetic CdCr2S4, the dielectric constant of HgCr2S4 becomes strongly enhanced in the region ...

Colossal Magnetoresistance is a Griffiths Singularity [PDF]
Physical Review Letters, 2002 It is now widely accepted that the magnetic transition in doped manganites that show large magnetoresistance is a type of percolation effect. This paper demonstrates that the transition should be viewed in the context of the Griffiths phase that arises ...

Colossal magnetoresistance of Nd-doped LaCaMnO3 polycrystalline ceramics [PDF]
Processing and Application of Ceramics, 2021 The cation doped polycrystalline compound La0.5Nd0.15Ca0.35MnO3 has been synthesized by a conventional solid state reaction method. The Rietveld analysis of the powder XRD of the composites reveals an orthorhombic structure with Pbnm space group symmetry.

Colossal electroresistance without colossal magnetoresistance in La0.9Sr0.1MnO3 [PDF]
Applied Physics Letters, 2007 The authors report on colossal electroresistance (ER) in the ferromagnetic insulator manganite La0.9Sr0.1MnO3. The single crystal samples exhibit a transition into a low resistive state above a certain threshold current. Pulsed measurements demonstrate that this transition is not a consequence of heating.
