Effect of "dipolar-biasing" on the tunability of tunneling magnetoresistance in transition metal oxide systems

P. Anil Kumar, D. D. Sarma

We observe an unusual tunneling magnetoresistance (TMR) phenomenon in a composite of La${}_{2/3}$Sr${}_{1/3}$MnO${}_3$ with CoFe${}_2$O${}_4$ where the TMR versus applied magnetic fiel…
