Self-Assembled La_0.67Sr_0.33MnO₃:CeO₂ Vertically Aligned Nanocomposite Thin Films on Flexible Mica

Crystals, 2023
Vertically aligned nanocomposite (VAN) thin film has attracted tremendous research interests owing to its multifunctionality, enhanced physical properties and multi-field coupling. However, VAN has rarely been demonstrated in flexible form, which hinders

Quasi-reversible Magnetoresistance in Exchange Spring Tunnel Junctions

, 2008
We report a large, quasi-reversible tunnel magnetoresistance in exchange-biased ferromagnetic semiconductor tunnel junctions wherein a soft ferromagnetic semiconductor (\gma) is exchange coupled to a hard ferromagnetic metal (MnAs).

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

2D transport and weak antilocalization effect in topological semimetal PtBi2 nanoflakes

AIP Advances
The striking anisotropic magnetoresistance and linear magnetoresistance observed in topological semimetals have attracted immense attention owing to their potential in magnetoresistance devices. We investigated the magnetotransport properties of trigonal

Linear magnetoresistance in metals: guiding center diffusion in a smooth random potential [PDF]

, 2015
We predict that guiding center (GC) diffusion yields a linear and non-saturating (transverse) magnetoresistance in 3D metals. Our theory is semi-classical and applies in the regime where the transport time is much greater than the cyclotron period, and ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Extrinsic magnetoresistance in semiconductors

Physica B: Condensed Matter, 1995
Abstract The extrinsic magnetoresistance of a metallically doped InSb sample has been investigated. At high temperatures, where no magnetoquantum oscillations occur, an additional linear magnetoresistance (LMR) arising from a difference in the Hall voltages can be observed.

Aharonov-Bohm effect and giant magnetoresistance in graphene nanoribbon rings

, 2013
We report a numerical study on Aharonov-Bohm (AB) effect and giant magnetoresistance in rectangular rings made of graphene nanoribbons (GNRs). We show that in low energy regime where only the first subband of contact GNRs contributes to the transport ...
