Abstract:
The concept & effort to develop radar absorbing materials (RAMs) has been gaining widespread interest to the researchers, mainly, working in the field of magnetic materials viz. hexaferrites. In this work, bulk M-hexaferrite with combined substitution of divalent ions Ca-Ba-Sr with trivalent La has been synthesized using standard ceramic method. Due to combined substitution of mixed valence ions the magnetic & conducting parameters found enhanced. The order of magnitude for dielectric constant lies in the range of 103 to 104& can favor to suppress microwave reflection. Following the truthiness of Iwauchi’s relation, a relation between mobility (µ) & dielectric constant ( ) was tried to achieve.
Keywords: M-hexaferrite, Iwauchi’s relation, mobility, dielectric constant
