Linear magnetoresistance in a topological insulator Ru2Sn3

open access: yesAIP Advances, 2017
We have studied magnetotransport properties of a topological insulator material Ru2Sn3. Bulk single crystals of Ru2Sn3 were grown by a Bi flux method. The resistivity is semiconducting at high temperatures above 160 K, while

Aharonov-Bohm effect and giant magnetoresistance in graphene nanoribbon rings

open access: yes, 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 ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Magetoresistance of RuO_2-based resistance thermometers below 0.3 K

open access: yes, 2001
We have determined the magnetoresistance of RuO_2-based resistors (Scientific Instruments RO-600) between 0.05 K and 0.3 K in magnetic fields up to 8 T. The magnetoresistance is negative around 0.5 T and then becomes positive at larger fields.

Magnetoresistance of Magnetite

open access: yesPhysica Status Solidi (a), 1972
The transversal magnetoresistance was studied in single crystals of natural magnetite for different temperatures between 300 and 77 °K and in fields up to 10 kG. For temperatures above the transition point, i.e. in the cubic phase, the magnetoresistance is positive and shows a maximum at 5 kG.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

open access: yesAdvanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Underlying Mechanisms and Tunability of the Anomalous Hall Effect in NiCo2O4 Films with Robust Perpendicular Magnetic Anisotropy

open access: yesAdvanced Science, 2023
Their high tunability of electronic and magnetic properties makes transition‐metal oxides (TMOs) highly intriguing for fundamental studies and promising for a wide range of applications. TMOs with strong ferrimagnetism provide new platforms for tailoring

Magnetotransport properties of La$_{1-x}$Ca$_x$MnO$_3$ (0.52 $\leq x \leq$ 0.75): signature of phase coexistence

open access: yes, 2017
We report the temperature and magnetic field dependence of transport properties in epitaxial films of the manganite La$_{1-x}$Ca$_{x}$MnO$_{3}$ in the overdoped region of the phase diagram for $x > 0.5$, where a charge--ordered (CO) and an ...
