Magnetic properties of MnZnTi and NiZn ferrite films deposited by laser ablation

Abstract

Structural and magnetic properties of NiZn and Zn ferrite thin films obtained by laser ablation deposition J. Appl. Phys. 97, 10G105 (2005); 10.1063/1.1854416Magnetic and structural properties of ultrafine Ni-Zn-Cu ferrite grown by a sol-gel method Angle dependence of the ferromagnetic resonance linewidth and two magnon losses in pulsed laser deposited films of yttrium iron garnet, MnZn ferrite, and NiZn ferriteThe magnetic behavior of MnZnTi and NiZn ferrite films, deposited by laser ablation, is studied comparatively to that of the bulk material, using a vibrating-sample magnetometer ͑VSM͒, transmission, and conversion electron Mössbauer measurements. Both the VSM and Mössbauer analysis show that the films exhibit the single phase pattern of the target material. Mössbauer hyperfine field values for films are close to those found for the bulk, and this accounts for the same saturation magnetization values determined by VSM. Laser ablated films exhibit a higher coercive field, which is explained in terms of the crystallite size distribution, with average values of 300-600 nm, as estimated from the Mössbauer line broadening.

Structural and magnetic properties of sol–gel Co2xNi0.5−x Zn0.5−xFe2O4 thin films

“…with thickness o1.0 mm) deposited on the reactor channel walls or via nanoparticles dispersed in a flowing liquid. Co-Ni-Zn ultrafine spinel type ferrites are possible candidates for microwave heating due to their moderate dielectric losses in the range between 2 and 15 GHz as well as large magnetic losses [1][2][3].…”

Fabrication and magnetic properties of Sol-Gel derived NiZn ferrite thin films for microwave applications

“…The methods employed have included pulsed laser deposition (PLD), 29,[36][37][38][39] alternative sputtering, 22,40 chemical bath deposition, 41,42 and spinspray methods. 30,31,35,43 In the cases of PLD and alternative sputtering, the resulting films were found to have high losses, 29,40 high coercivities, 22,[38][39][40] or high stress-induced anisotropy fields. 36,37 The magnetic and high frequency properties of the films made using the chemical bath deposition method were not investigated, however this method yielded films with a flake morphology.…”

Structural investigations and magnetic properties of sol-gel Ni0.5Zn0.5Fe2O4 thin films for microwave heating

“…Ni-Zn ultrafine spinel type ferrites are possible candidates for microwave heating due to their moderate dielectric losses in the range between 2 and 15 GHz as well as large magnetic losses. [1][2][3] Spinel ferrites have the general molecular formula M 2+ Fe 2 3+ O 4 2− , where divalent metal cations M 2+ and Fe 3+ occupy tetrahedral ͑A͒ and octahedral ͑B͒ interstitial positions of the fcc lattice formed by O 2 2− ions. Both dielectric and magnetic properties of these oxides depend on the type of cations and their distribution among the two interstitial positions, which in turn depends on the method of synthesis and calcination conditions 4,5 and the film density.…”
