K-band microwave absorption analysis of sol–gel synthesized cobalt-substituted zinc spinel ferrites
Cobalt-substituted zinc spinel ferrites having chemical composition Zn 1− x Co x Fe 2 O 4 with stoichiometric proportion ‘ x ’ equals 0.00, 0.25, 0.50, 0.75, and 1.00 have been synthesized by sol–gel citrate route sintered at 1000 °C for 6 h. All the fabricated specimens have been characterized by u...
