Development of magnetically switchable high permittivity microwave dielectrics using La(Al1‐xFex)O3

The introduction of transition metal doping, particularly Fe3+, into high‐performance microwave dielectrics can make “smart” materials that switch between a high‐Q, low loss state and a low‐Q, high loss state using a small external magnetic field. In this study, the dielectric and magnetic propertie...
