We report on a high-field magnetotransport study of KTaO3 single crystals.This material is a promising candidate to study in the extreme quantum limit(EQL). By photocarrier doping with 360 nm light, we have observed a significantpositive, non-saturating, and linear magnetoresistance at low temperaturesaccompanied by a vanishing Hall coefficient. When cooled down to 10 K andsubjected to a magnetic field of 12 T, the value of magnetoresistance of KTaO3(100) is increased by as much as 433%. Such behavior can be attributed to allelectrons occupying only the lowest Landau level in the EQL. In this state, aquantum magnetoresistance is produced. This result provides novel insights intothe next generation of magnetic devices based on complex materials and adds anew family of materials with positive magnetoresistance.
