چکیده
Abstract In this article, we report the observation of extremely large non-saturating linear magnetoresistance (MR) in antimony (Sb) crystal. An 43 000% at 2 K and unsaturating MR ?70% room temperature is observed magnetic field 9 T. Hall measurements reveal a very high mobility ?3.8 × 10 4 cm V s ?1 charge carriers strong dependence carrier concentration mobility. The respective scaling crossover ( B c ) from quadratic to with inverse describes classical origin crystal as suggested by Parish Littlewood model for disordered systems.

Extremely large magnetoresistance in few-layer graphene/boron–nitride heterostructures
Understanding magnetoresistance, the change in electrical resistance under an external magnetic field, at the atomic level is of great interest both fundamentally and technologically. Graphene and other two-dimensional layered materials provide an unprecedented opportunity to explore magnetoresistance at its nascent stage of structural formation. Here we report an extremely large local magnetor...
متن کاملLarge linear magnetoresistance in heavily-doped Nb:SrTiO3 epitaxial thin films
Interaction between electrons has long been a focused topic in condensed-matter physics since it has led to the discoveries of astonishing phenomena, for example, high-Tc superconductivity and colossal magnetoresistance (CMR) in strongly-correlated materials. In the study of strongly-correlated perovskite oxides, Nb-doped SrTiO3 (Nb:SrTiO3) has been a workhorse not only as a conducting substrat...
متن کاملLarge magnetoresistance of electrodeposited single-crystal bismuth thin films
Single-crystal bismuth thin films 1 to 20 micrometers thick were fabricated by electrodeposition and suitable annealing. Magnetoresistance up to 250 percent at 300 kelvin and 380,000 percent at 5 kelvin as well as clean Shubnikov-de Haas oscillations were observed, indicative of the high quality of these films. A hybrid structure was also made that showed a large magnetoresistive effect of 30 p...
متن کاملQuantum linear magnetoresistance in multilayer epitaxial graphene.
We report the first observation of linear magnetoresistance (LMR) in multilayer epitaxial graphene grown on SiC. We show that multilayer epitaxial graphene exhibits large LMR from 2.2 K up to room temperature and that it can be best explained by a purely quantum mechanical model. We attribute the observation of LMR to inhomogeneities in the epitaxially grown graphene film. The large magnitude o...
متن کاملBipolar-driven Large Magnetoresistance in Silicon
Magnetoresistance (MR) effect in non-magnetic silicon has gained a renewed interest in recent years because the effect is large and shows non-saturating (linear) magnetic field dependence, which makes it a good candidate for magnetic field sensing applications.[1-3] It is known that the presence of “static” inhomogeneities like impurities, defects, and voids in non-magnetic material generate la...
