摘要: Abstract Dielectric constant ( e ) of Sn +4 /Nb +5 doped Mn-Zn ferrites has been measured as a function dopant concentration, frequency and temperature. At intermediate concentrations dopant, an unusual behaviour dielectric dispersion observed due to the occurence dimensional resonance thus interesting results are obtained in study variation with frequency. For these specimens, addition usual , increase is at two regions plot log  versus f support ferromagnetic behaviour. Studies loss temperature have also carried out know above said beyond magnetic Curie Results explained on basis correlation between conductivity constant, space charge polarisation, grain structure additional phase formation.
