一种由FeGaB薄膜和PZN - PT单晶片组成的新型多铁性异质结构显示出该异质结构的铁磁共振（FMR）频率可通过电场进行巨大的调谐（见图）。电场诱导的5.82 GHz的铁磁共振频率总变化是迄今为止报道的最大值。FeGaB/PZN - PT多铁性异质结构是宽带静电可调谐微波器件的有希望的候选材料。
A novel multiferroic heterostructure consisting of a FeGaB thin film and a PZN-PT single crystal slab shows giant tunability of the ferromagnetic resonance (FMR) frequency of the heterostructure by electric field (see figure). The overall electric-field-induced FMR frequency change of 5.82 GHz is the largest reported so far. FeGaB/PZN-PT multiferroic heterostructures are promising candidates for wide-band electrostatically tunable microwave devices.
