Effect of Ho3+ substitutions on the structural and magnetic properties of BaFe12O19 hexaferrites

Structural, Magnetic and Microwave Properties of Eu-doped Barium Hexaferrite Powders

“…It is concluded that a rare earth element, Eu, acts as a grain growth inhibitor, in agreement with other reports [19][20][21].…”

Structural, dielectric and magnetic properties of Cr–Zn doped strontium hexa-ferrites for high frequency applications

“…From the viewpoint of microwave devices, ferrites are used into an alternating magnetic field because of their high electrical resistivity, low eddy current loss and excellent magnetic property in high frequency as compared with metal magnetic materials. M-type hexa-ferrites are more useful, for high frequency (GHz) applications than soft ferrites due to their high magneto crystalline anisotropy which resulted in very low residual losses [9][10][11][12]. Several synthesis techniques have been used to prepare and tailor the properties of strontium hexa-ferrite nanoparticles [13][14][15][16][17].…”

Remarkable magnetization with ultra-low loss BaGd x Fe 12−x O 19 nanohexaferrites for applications up to C-band

“…Li et al [1] investigated the magnetic and microwave properties of La-doped hard ferrites, but they might not have succeeded in obtaining the quality hysteresis curves. Rai et al [2] reported very low values of M s and H c for BaFe 12 O 19 ferrite. In fact, many researchers have investigated M-Type hard ferrites in the bulk form [2], but the literature on nanohexaferrites at microwave frequency range is scarce.…”

In fact, many researchers have investigated M-Type hard ferrites in the bulk form [2], but the literature on nanohexaferrites at microwave frequency range is scarce. Gd 3 þ substituted barium nanohexaferrites with high ferromagnetic resonance frequency and high permeability is most suitable for circulator, filters, inductor cores, electromagnetic noise absorber, medical devices, computers and other microwave devices that send, receive and manipulate electromagnetic signals in ultra-high frequency region [3,4].…”
