Studies into the underlying mechanisms of organic magnetoresistance [PDF]
, 2012 PhDThe organic magnetoresistance effect has been observed to alter the current and efficiency of organic light emitting diodes where no magnetic materials are present. As yet, no consensus has been reached in the literature regarding the origin of the

Magnetotransport Signatures of Spin-Orbit Coupling in High-Temperature Cuprate Superconductors. [PDF]
Adv Sci (Weinh)Large angle‐dependent magnetoresistance and planar Hall effects emerge at the superconducting transition of YBa2Cu3O7−x$\mathrm{YBa_2Cu_3O_{7-x}}$ thin films. These anomalous transport signatures, absent in the normal state, point to spin‐polarized quasiparticle dynamics enabled by an unexpected spin–orbit coupling landscape in cuprate superconductors,

Colossal magnetoresistance in a nonsymmorphic antiferromagnetic insulator [PDF]
npj Quantum Materials, 2020 Here we investigate antiferromagnetic Eu5In2Sb6, a nonsymmorphic Zintl phase. Our electrical transport data show that Eu5In2Sb6 is remarkably insulating and exhibits an exceptionally large negative magnetoresistance, which is consistent with the presence

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 when disorder suppresses a magnetic transition.

Physical review B, 2021 Colossal magnetoresistance is of great fundamental and technological significance and exists mostly in the manganites and a few other materials. Here we report colossal magnetoresistance that is starkly different from that in all other materials.

Room‐Temperature Colossal Magnetoresistance in Terraced Single‐Layer Graphene [PDF]
Advances in Materials, 2020 Disorder‐induced magnetoresistance (MR) effect is quadratic at low perpendicular magnetic fields and linear at high fields. This effect is technologically appealing, especially in 2D materials such as graphene, since it offers potential applications in ...

Percolation mechanism for colossal magnetoresistance [PDF]
Computational Materials Science, 1998 We argue that colossal magnetoresistance is a critical phenomenon and propose a mechanism to describe it. The mechanism relies on the halfmetallic behavior of the materials showing colossal magnetoresistance, and yields a correlated percolation model that, we argue, captures all qualitative features of colossal magnetoresistance, above as well as below

Striping of orbital-order with charge-disorder in optimally doped manganites
Nature Communications, 2021 Manganite perovskites display the intriguing property of colossal magnetoresistance (CMR), but only at very specific doping values. Now, a detailed crystallographic analysis of a prototype system reveals a novel type of orbital ordering that coexists ...
