Unusual field dependence of remanent magnetization in granular CrO2: possible role of piezomagnetism
A. Bajpai, R. Klingeler, N. Wizent +3
We present low field thermoremanent magnetization (TRM) measurements in granular CrO2 and composites of ferromagnetic (FM) CrO2 and antiferromagnetic (AFM) Cr2O3. TRM in these samp…

Observation of fluctuation induced tunneling conductance in polycrystalline CrO2
A. Bajpai, A. K. Nigam
Intergranular conduction in half metallic CrO2 is known to occur through a combination of spin dependent tunneling (driven by Coulomb Blockade (CB) effects) together with certain s…

Magnetoresistance in granular CrO2 : influence of crystallographic and magnetic microstructure
A. Bajpai, A. K. Nigam
We report magnetotransport measurements on high purity sintered samples of spintronic CrO2 in an unexplored crystallographic regime between 5-300 K. The negative magnetoresistance…
