Magnetic Flux Density Computation in Voltage-Controlled Lanthanum Strontium Manganite Materials

This work reports for the estimation and computation of the generated magnetic field in smart lanthanum strontium manganites oxide (LSMO) materials with the application of DC electric field. With electrostatic bias field, it is assumed that induced electric current will modify the electrical behavior of the electrode-manganite interface, and gives rise to a local magnetic field. The applied electric field and the generated magnetic field lead to the reduction in the junction resistance. This work gives an estimation of this local generated magnetic field by applying the Ampere's circuital law. The results are helpful for anyone working on the effect of electric field/current on manganites.
