Effect of dopants on barium hexaferrite

Samples of Ba1.266Ti2.956 Fe7.6Li0.844O19 hexaferrite have been prepared using anatase and rutile phases of TiO2 by classical ceramic route. A pure sample of Ba Fe12O19 has also been prepared for comparison. The structural, electrical and magnetic characteristics have been studied by XRD, SEM, FTIR, two probe method, hysteresis loop and susceptibility curves. The samples exhibit hexagonal magne...

Barium Hexaferrite Thick Films for Microwave Absorbers and Circulators

Barium hexaferrite (BaHF) with the chemical formula BaFe12O19 is a hard magnetic material and has high magnetic anisotropy field (MAF), 17 kOe. The easy direction of magnetization corresponds to the crystallographic c-axis and BaHF particles orient in this direction when are exposed to an external magnetic field. Because of the high MAF, a ferromagnetic resonant frequency appears from 45 to 50 ...

Phase Frequency Detector Using Transmission Gates for High Speed Applications

In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
