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…
