Barium ferrite thick films for microwave applications

Barium hexaferrite suspensions for electrophoretic deposition

“…Thick films from different materials, like oxides, metals, composites, softmagnetic materials, and many others, can be prepared with EPD [8], and thick films of magnetic oxides are frequently used for high-frequency devices in electronics. For example, thick films based on spinel ferrites are used for high-frequency devices at around 1 GHz [9] and thick films based on barium hexaferrite ðBaFe 12 O 19 Þ can be used for high-frequency devices above 40 GHz [10,11]. Typically, thick magnetic films are prepared with screen printing, spray coating, and tape casting [12][13][14].…”

Impedance spectroscopy analysis of BaFe12O19 M-type hexaferrite obtained by ceramic method

“…Hexagonal barium hexaferrite (BaFe 12 O 19 ), often denoted as M-type BaM, is widely used in electronics, e.g. permanent magnets, particulate media for magnetic recording [1][2][3][4] and microwave devices. These last ones can be found in multilayer chip inductors as the main surface mount devices (SMDs) usually operated in the 0.3-1 GHz frequency range [5].…”

Influence of annealing in vacuum and in air on magnetic, crystallographic and morphological properties of thin YIG films

“…To obtain films of good qualities, all conditions and parameters concerning the background pressure, purity and flow rate of argon, the distance between the target and the substrate, the radio-frequency power of the magnetron cathode etc…, are specified in previous works [11][12][13].…”
