Influence of Nd3+ substitution on the microstructure and electromagnetic properties of barium W-type hexaferrite

Role of Ce–Mn substitution on structural, electrical and magnetic properties of W-type strontium hexaferrites

“…in W-type hexagonal ferrites to enhance their different properties. However in the last few years researchers divert their attention to substitute rare earth metal at various sites in the Wtype hexagonal ferrites such as Y, Er, Ho, Sm, Nd, Gd, Ce [6], Dy, Nd, Pr [16], Y, Er, Ho, Sm, Nd, Gd, Ce [17], Nd [18] because these substitution changes the magnetic interactions and therefore enhances the magnetic properties [19]. Rare earth ions have typical relaxation characteristics which may affect the electromagnetic properties of ferrite magically [20].…”

Barium hexaferrite synthesis by oxalate precursor route

“…Solid state reaction method is used for the fabrication of barium based hexaferrites. The sites occupied by Fe ions can be replaced with Al, Co, Zr, Mn, Zn, Sm and Sn, or rare earth elements such as Ho 3+ , Nd 3+ [22][23][24][25]. In this study, the oxalate precursor technique was used to synthesize nanocrystalline barium ferrite with high saturation magnetization and narrow size distribution.…”

A new microwave absorber based on antimony-doped tin oxide and ferrite composite with excellent electromagnetic match

“…As a result, considerable interests have been attracted on microwave absorbers [1][2][3][4]. For the W-type barium ferrites, they are suitable for electromagnetic interference suppression and radar absorbent material (RAM) due to their strong magnetic losses at gigahertz frequency [5][6][7]. However, single conventional ferrite is hardly to satisfy the appropriate electromagnetic match which is essential for strong absorption behavior in wide frequency range.…”
