Insight of structural, dielectric and spectroscopic characteristics of Ba0.6Sr0.4-xYbxFe12-yCoyO19 M-type hexaferrite

Experimental and Theoretical Realization of Morphology and Frequency Tuned Charge Transport Dynamics in Co-Zn Doped SrM Hexaferrite: Electrical, Impedance and Relaxation Realm

“…Meanwhile, the band shifts towards higher frequency due to a reduction in bond length. Hence, the FTIR findings are in good agreement with the XRD data, as shown by Gulbadan S. and Rehman M. 25,26 For all samples, the absorption peak around 580-590 cm −1 is distinguished which may be associated with the Sr-O stretching vibration band. 27 Similar results were observed in Co substituted M-type barium and strontium hexaferrite, respectively.…”

Effect of ferromagnetic cobalt on characteristics of coercive Aluminium substituted BaFe11.5Al0.5O19 hexaferrites

“…By using the Celref software version-3, the lattice parameters were successfully refined. Vibrating-sample magneto-meter (NIM-2000HF) was used to find magnetic hysteresis loops, and then H c and M s values were estimated from the hysteresis loops [37].…”

“…Recent studies have demonstrated that M-type hexaferrites with rare earth (Re) metal substitutions have better magnetic characteristics. The enhancement is mainly attributed to a rise in the coercive field and magneto-crystalline an-isotropy [1,37]. According to Wang et al, replacing Sm ions produced fine powders of M-type hexa-ferrites, increasing the coercive field.…”

Influence of Gd and Ni doping on the structural, morphological, and magnetic properties of M-type calcium hexaferrite

“…[8][9][10][11] According to structural differences, ferrites have been categorized into four primary families: spinel, orthoferrite, garnet, and hexagonal, 12,13 ), where B represents a bivalent cation such as Ba 2+ , Sr 2+ , Pb 2+ , Cd 2+ , and Ca 2+ and Me represents the bivalent transition metals. 9,14,15 Due to the superexchange interaction, all hexaferrites exhibit ferrimagnetic behaviour. 12 The M-type hexaferrites are widely used in industry because of their comparatively low cost and ease of synthesis.…”

“…8–11 According to structural differences, ferrites have been categorized into four primary families: spinel, orthoferrite, garnet, and hexagonal, 12,13 in which hexagonal ferrites are further classified into six categories based on the chemical structures such as X-type (B 2 Me 2 Fe 28 O 46 ), Y-type (B 2 Me 2 Fe 12 O 22 ), Z-type (B 3 Me 2 Fe 24 O 41 ), M-type (BFe 12 O 19 ), W-type (Bme 2 Fe 16 O 27 ), and U-type (B 4 Me 2 Fe 36 O 60 ), where B represents a bivalent cation such as Ba 2+ , Sr 2+ , Pb 2+ , Cd 2+ , and Ca 2+ and Me represents the bivalent transition metals. 9,14,15 Due to the superexchange interaction, all hexaferrites exhibit ferrimagnetic behaviour. 12 The M-type hexaferrites are widely used in industry because of their comparatively low cost and ease of synthesis.…”
