1Impact of In^(3+) cations on structure and electromagnetic state of M-type hexaferrites显示文摘The solid solutions of In^(3+) doped M-type strontium hexaferrites were produced using a conventional solid-state reaction method,and Rietveld analysis of the neutron diffraction patterns was conducted.In^(3+) cations occupy octahedral (4f_(Ⅵ)and 12 k) and tetrahedral (4f_(Ⅳ)) positions (SG=P6_(3)/mmc(No.194)).The average particle size is 837–650 nm.Curie tempearature (T_(C)) of the compounds monotonically decreased down to~520 K with increasing x.A frustrated magnetic state was detected from ZFC and FC magnetizations.saturation magnetization (M_(s)) and effective magnetocrystalline anisotropy coefficient (k_(eff)) were determined using the law of approach to saturation.A real permittivity (ε″) maximum of~3.3 at~45.5 GHz and an imaginary permittivity (ε′) of~1.6 at~42.3 GHz were observed for x=0.1.A real permeability (μ′) maximum of~1.5 at~36.2 GHz was observed for x=0.Aμ″imaginary permeability maximum of~0.8 at~38.3 GHz was observed for x=0.1.The interpretation of the results is based on the type of dielectric polarization and the natural ferromagnetic resonance features.Vitalii Alexandrovich Turchenko Sergei Valentnovich Trukhanov Vladmir Grigor'evich Kostishin Francua Damay Florance Porcher Denis Sergeevich Klygach Maxim Grigor'evich Vakhitov Lyudmila Yur'evna Matzui Olena Sergeevna Yakovenko Bernat Bozzo Ignasi Fina Munirah Abdullah Almessiere Yassine Slimani Abdulhadi Baykal Di Zhou Alex Valentinovich Trukhanov 2022Journal of Energy Chemistry2022,31,6:0
