ABSTRACTInvestigations on microwave magneto-electric (ME) interactions at 1-10 GHz have been carried out on yttrium iron garnet (YIG)-lead zirconate titanate (PZT) and YIG-lead magnesium niobate lead titanate (PMN-PT) bilayers. Ferromagnetic resonance is a powerful tool for such studies. An electric field E applied to the composite produces a mechanical deformation in PZT or PMN-PT, resulting in a shift in the resonance field for YIG. Information on the nature of high frequency ME coupling has been obtained from data on resonance field shift vs E. A cavity resonator or stripline structure was used. The measured ME interactions are in the range 1-5 Oe cm/kV. The coupling strength has been found to be dependent on magnetic field orientation. The strongest interaction is measured in YIG-PZT systems. The design and characterization of ferromagnetic resonance based, electric field tunable ME resonators and filters are discussed.

In this work, ferroelectric SbSI shows a giant electrocaloric effect at room temperature under very low electric field shift of 0.37 kV cm-1. It is shown that the cooling ΔT per unit field MVm-1 is 2.97. This value is significantly larger, and is comparable with the value of 0.254 for PbZr 0.95 Ti 0.05 O 3 thin film under electric field shift of 30 kV cm-1. Moreover, the reduction in operating temperature opens up many more possibilities and widens the potential for applications in cooling systems.

Electric Field Change

In this work, electrocaloric properties of Pb ( Mg 1/3 Zr 2x/3 Nb 2(1-x)/3) O 3-x/3 polycrystalline ceramics for different stoichiometric compositions have been investigated. The results show that largest changes (ΔT) are in range of 1.07 to 4.84 K in 10 kV cm-1 electric field change. These values are significantly large, and are comparable with values of other lead-containing ceramics under the same or larger electric field shift. The conclusion is that these materials are excellent candidates for working materials in refrigeration and liquefaction devices in a wide temperature range.
