Large linear magnetoresistance in single HgSe crystals induced by low-concentration Co impurity

A large linear magnetoresistance up to 600% at a magnetic field of 9 T was discovered in single HgSe:Co crystals with a low Co content (not exceeding 0.035 at. %). This was accompanied by a noticeable rise in relative magnetoresistance in comparison with undoped HgSe. An analysis of sample inhomogen...

Description
Summary:A large linear magnetoresistance up to 600% at a magnetic field of 9 T was discovered in single HgSe:Co crystals with a low Co content (not exceeding 0.035 at. %). This was accompanied by a noticeable rise in relative magnetoresistance in comparison with undoped HgSe. An analysis of sample inhomogeneity is presented. Possible sources of linear magnetoresistance in HgSe:Co are discussed.
