18. 3 possesses ferroelectric properties only below 32.5 K (namely, it exhibits spontaneous electric polarization). Thus at our working temperatures (about room temperature) this material is actually paraelectric (its electric dipoles behave under electric field in an analogous manner to magnetic dipoles under magnetic field in paramagnetic materials). Nevertheless, it is customary in the literature to refer to this material as ferroelectric.

27. The quality factor can be controlled during crystal manufacture (we requested the highest possible Q).
28. Inspection of Fig. 7 shows that the largest increase in the EPR signal occurs when the ring resonator is inside the sample tube. This interesting, novel, and very efficient configuration can be obtained for liquid samples by using a relatively large sample tube (i.d. ∼3 mm) where the ring resonator is inserted inside the sample tube, prior to the sample preparation process. However, we have found in our experiments that when the solvent has high dielectric losses, such configuration may result in the decrease of Q. This is probably due to the strong electric field component, which exists outside our rectangular ring resonator (cf., Fig. 6).
