Magnetic properties of c-axis oriented Sr0.8La0.2Fe11.8Co0.2O19 ferrite film prepared by chemical solution deposition

Structure, magnetic and magneto-optical properties of La-Ca-Co substituted strontium ferrites

“…It has been reported that partial substitutions of La 3+ and/or La 3+ -Co 2+ into strontium ferrites [9][10][11] improve significantly the magnetic properties. Other cations such as Sm 3+ , Nd 3+ , Pr 3+ , Pb 2+ and cation combinations such as Nd 3+ -Co 2+ , Sn 4+ -Mg 2+ , Ru 4+ -Co 2+ , Co 2+ -Ti 4+ -Bi 3+ have been attempted to improve the properties of strontium ferrites for potential applications.…”

Structural, dielectric and magnetic properties of Nd-doped Co2Z-type hexaferrites

“…The dielectric and magnetic properties of hexaferrites such as, permittivity, permeability, coercivity and saturation magnetization can be controlled by substitution of divalent or trivalent ions. It is reported that ions substitution may improve their properties and characteristics [5][6][7][8][9][10]. Rare-earth elements (R) have typical relaxation characteristics, which can affect the electromagnetic properties of ferrite strongly [11][12][13][14][15].…”

Preparation, and magnetic and electromagnetic properties of La-doped strontium ferrite films

“…Otherwise the absorbers depend on magnetic polarization attenuation such as magnetic hysteresis loss, domain wall resonance, after effect loss [9,[16][17][18]. The magnetoplumbite structured strontium ferrite is an appropriate candidate because of its high saturation magnetization, fairly larger magneto-crystalline anisotropy, excellent chemical stability and magnetic moment aligned along the c-axis and good microwave absorption properties [18][19][20][21][22]. Considerable effort has been directed to the investigations of bulk hexagonal ferrite [19], and recently the thin hexagonal ferrite films have been also widely studied [20][21][22][23][24][25][26].…”

“…For example, Zi et al [20] prepare a Sr 0.8 La 0.2 Fe 11.8 Co 0.2 O 19 ferrite film on a (0 0 1) sapphire substrate by chemical solution deposition and study the structural characteristics and the magnetic anisotropy of the as-deposited film. Several techniques have been employed to deposit thin films of ferrite materials such as liquid and vapor phase epitaxy [27], sputtering [28], and plasma spraying [29], pulsed laser deposition [30][31][32], sol-gel method [26,33], ceramic process [34,35], etc.…”
