Structural and magnetotransport study of SrTiO3-δ/Si structures grown by molecular beam epitaxy
… shows a reproducible trend of a positive magnetoresistance (MR) at 300K, which turns to a negative MR effect between 200K and 100K, and turns up again to a positive MR at 3K. Interestingly, at 3K, the MR starts to turn down again at high fields.

COMPOSITION AND PRESSURE DEPENDENT STUDY ON WEYL SEMIMETAL Mo1-xWxTe2
… behavior for all dop- ing levels. Transverse magnetoresistance (MR) measurements show that the parent compounds exhibit large non-saturating MR, which might result from electron-hole compensation, whereas the doped compounds have low MR values, indicating doping- induced electron-hole …

The development of magnetic tunnel junction fabrication techniques
The discovery of large, room temperature magnetoresistance (MR) in magnetic tunnel junctions in 1995 sparked great interest in these devices. Their potential applications include hard disk read head sensors and magnetic random access memory (MRAM). However, the fabrication of repeatable, high …

Magneto-transport properties of manganite/secondary phase inhomogeneous systems
… to the spin tunneling effect and the low field magnetoresistance (MR) effect, whose peak value for LBMO is enhanced from 3% to -3.3 %, -3.5 % and -3.7% with TiO2 addition for x= 0.02, 0.04 and 0.06 ratio. An improvement in magnetocaloric (MC) properties in comparison with LBMO at the same …

Spin transport in few-layer graphene
… regarding the interpretation of local magnetoresistance (MR), where the spin-valve signal can be confused with tunnelling anisotropic magnetoresistance (TAMR) at the contacts. The magnetisation-reversal in unpatterned films of La0.67Sr0.33MnO3 (LSMO) on substrates of NdGaO3 (001), …

Fabrication of Core-Shell Nanoparticles
… a variation of magnetic field is referred to as magnetoresistance (MR). Magnetoresistance was observed in the pressed Co-Au core-shell pellet. Both the fresh Co-Au and annealed core-shell nanoparticle followed the metallic conduction behavior. No MR was observed in the Co-Cu and FeCo-Cu …

Control of Superconductivity in Cuprate/Manganite Heterostructures
… of YBCO switches to superconductivity, a magnetoresistance(MR) peak was observed when the F layers were antiparallel. The MR effect increased with decreasing bias current and temperature, characteristic of a pseudo-spin valve. The result is suggestive of spin transport across the YBCO …

Nanomagnetismus von epitaktischen Fe(110)- und CrO 2 (100)-Strukturen im Hinblick auf potentielle spinelektronische Anwendungen
… Center in San Jose, California, tunneling magnetoresistance (TMR) structures (chromium dioxide/MgO/CoFe) were prepared that showed positive and negative TMR ratios of about 7%. Furthermore a detailed study of the domain configurations and the magnetization reversal in small chromium dioxide …

EXPLORATION OF NEW MULTIFUNCTIONAL MAGNETIC MATERIALS BASED ON A VARIETY OF HEUSLER ALLOYS AND RARE-EARTH COMPOUNDS
… shown that magnetic entropy changes (SM) and magnetoresistance (MR) associated with this transformation are larger and the hysteresis effect is significantly lower when compared to that associated with paramagnetic-ferromagnetic transitions or ferromagnetic-antiferromagnetic/paramagnetic …

Study on graphene-based nanocomposites with special magnetoresistance properties
Magnetoresistance (MR) refers to the change of a material’s electrical resistance under the presence of an external magnetic field. The discovery of new MR phenomena (e.g., giant magnetoresistance (GMR) and tunneling magnetoresistance (TMR)) since the 1980s initiates the revolution of novel …

Realisation of De Gennes’ Absolute Superconducting Switch and Magnetic Exchange Field Effects at Metallic and Superconductor Interfaces
… by investigating the longitudinal and Hall magnetoresistance (MR) in EuS/Au/EuS switches of varying Au thicknesses. We observe that the MEF suppresses the localisation effect in thin Au spacers (dAu < 6 nm), resulting in the P-state resistance being larger than that the AP-state resistance …
