Magnetic resonance investigation of multiferroic materials

Text

Multiferroic materials with magnetoelectric coupling are attractive for spintronic and random access memory applications and telecommunication. We study these materials by EPR and NMR techniques in wide temperature range (3-600 K) and magnetic fields (+/-15 kOe). In addition to the spectroscopic studies, magnetoelectric (ME) coupling is measured as well. The ME coefficients are determined by a dynamic method as a function of bias magnetic field at a small ac field by measuring the current across the sample or voltage/polarization utilizing a high-sensitive lock-in-amplifier.
