Anomalous magnetic and transport properties of InSb(Mn) crystals near metal-insulator transition

AIP Advances, 2018
In Mn-doped InSb single crystals an unusual, for nonmagnetic semiconductors, dependence on manganese concentration have been revealed for magnetization, conductivity, magnetoresistance and the Hall effect in the range NMn= (1÷2)×1017cm-3.

Consequences of the CMR effect on EELS in TEM

, 2017
Double perovskite oxides have gained in importance and exhibit negative magnetoresistance, which is known as colossal magnetoresistance (CMR) effect. Using a La$_2$CoMnO$_6$ (LCM) thin film we prove that the physical consequences of the CMR effect do ...

Colossal electroresistance in ferromagnetic insulating state of single crystal Nd$_0.7$Pb$_0.3$MnO$_3$

, 2007
Colossal electroresistance (CER) has been observed in the ferromagnetic insulating (FMI) state of a manganite. Notably, the CER in the FMI state occurs in the absence of magnetoresistance (MR).

Extreme Transverse Magnetoresistance in TiZn16

Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
Extreme magnetoresistance is observed in TiZn16, despite its metallic nature and a highly complex electronic structure with multiple electron and hole Fermi surfaces. High‐magnetic‐field measurements further revealed the presence of a cylindrical open orbit, which may help resolve the origin of the extreme magnetoresistance.

Electronic and Magnetic Reconstructions in Manganite Superlattices

, 2013
We investigate the electronic reconstruction at the interface between ferromagnetic metallic (FM) and antiferromagnetic insulating (AFI) manganites in superlattices using a two-orbital double-exchange model including superexchange interactions, Jahn ...

Effects of conjugated polymer on the magnetotransport properties in La0.7Sr0.3MnO3 ferromagnetic electrodes

AIP Advances, 2013
Magnetotransport of La0.7Sr0.3MnO3 (LSMO)/regioregular poly3-hexylthiophene (rr-P3HT) interfaces were studied at 5–300 K to gain insight of spin transport in polymer coated LSMO.

Giant semiclassical magnetoresistance in high mobility TaAs2 semimetal

, 2016
We report the observation of colossal positive magnetoresistance (MR) in single crystalline, high mobility TaAs2 semimetal. The excellent fit of MR by a single quadratic function of the magnetic field B over a wide temperature range (T = 2-300 K ...
