Hi , I would like to know if there is any material , a dielectric like the one used in a capacitor , whose dielectric permittivity could be altered , like increased or decreases , I'm not talking about older type capacitors which had plates on a rotor that could be adjusted so that one could change the plate area.
I mean more like a material which is a dielectric but whose dielectric permittivity could be changed by some interaction , electric, magnetic maybe ?
