Abstract
Mn–Zn ferrite substituted with rare earth ions have been investigated by means of positron annihilation lifetime spectroscopy
(PALS). The variations of lifetime parameters tav, I2, and k with ionic radius of rare earth ions, grain size and electrical resistivity
for all samples have been studied. The intergranular pores increase with increasing the ionic radius of rare earth ions and grain
size of the samples
