原始语种摘要: Abstract(#br)The synthesis, characterization and magneto-transport investigations on the single crystals of semimetal NbAs 2 in a temperature range varying from 300 K to 2.5 K with a magnetic field up to 14 T are reported. The temperature dependence of resistivity that exhibits a metallic behavior without a magnetic field is seen to show an upturn as the magnetic field is applied resulting in a very large magneto-resistance. The upturn temperature displays a systematic increase with increasing fields. It is shown that this behavior of magneto-resistance can be understood in terms of the Kohler's scaling relation rather than in terms of the existence of a critical magnetic field inducing a metal to insulator transition. Through careful experiments, including angular dependence of...
