Abstract: The coexistence of electric polarization and magnetization in multiferroic materials provides great opportunities for realizing magnetoelectric coupling, including electric field control of magnetism, or vice versa, through a strain mediated magnetoelectric interaction effect in layered magnetic/ferroelectric multiferroic heterostructures . Strong magnetoelectric coupling has been the enabling factor for different multiferroic devices, which however has been elusive, particularly at RF/microwave frequencies. In this presentation, I will cover the most recent progress on different magnetic and multiferroic heterostructures and devices, including nanoelectromechanical system magnetoelectric sensors with picoTesla sensitivity by usingFeGaB/Al2Omultilayers, new integrated GHz magnetic inductors based on solenoid structures with FeGaB/Al2O3 and FeCoB/Al2O3 multilayers exhibiting >150% enhanced inductance and quality factor ~20 at GHz frequencies over their air core counterparts, power efficient voltage tunable magnetoelectric inductors with inductance tunability of 50%~150% at GHz, etc. These novel voltage tunable GHz inductors show great promise for applications in radio frequency integrated circuits. At the same time, we will demonstrate other tunable multiferroic devices, including multiferroic voltage tunable bandpass filters [6], tunable bandstop filters, tunable phase shifters, multiferroic antennas,and spintronics, etc.
