Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

The infeasibility of constant output power in a constant-current-fed class-E power inverter

open access: yesIEEE Transactions on Industrial Electronics, 1991
It is shown that it is impossible to configure a constant-current-fed class E inverter to provide constant output power independent of load, except for a trivial circuit in which the output power is zero. The basic equations and the requirements for load-independent power are discussed. >
