SCS-assisted production of EuFeO3 core-shell nanoparticles: formation process, structural features and magnetic behavior

Магнитные свойства нанокристаллического материала на основе Bi-=SUB=-2-=/SUB=-Fe-=SUB=-4-=/SUB=-O-=SUB=-9-=/SUB=-

“…Метод растворного горения является эффективным для получения нанокристаллических ферритов различного состава, в том числе Bi 2 Fe 4 O 9 , при достаточно высокой температуре, поскольку быстрое протекание реакции горения не способствует рекристаллизационному росту частиц [11][12][13][14][15][16][17][18][19][20][21][22].…”

“…Мёссбауэровские исследования состояния ионов железа в сложных оксидах, в том числе нанокристаллических, дают полезную информацию о механизмах их образования и особенностях магнитного поведения [1,7,12,13,[15][16][17][24][25][26][27]. Данные таких экспериментов, представленные в работах [1,7,17,27…”

Evaluation of the Effect of Minor Additions in the Crystallization Path of [(Fe0.5Co0.5)0.75B0.2Si0.05]100-xMx Metallic Glasses by Means of Mössbauer Spectroscopy

“…Moreover, the Mössbauer signal is directly proportional to the number of Fe atoms present in each phase, thus allowing the quantification of the relative amount of Fe atoms in a particular region, either crystalline or amorphous. This technique has been successfully used in combination with other conventional characterization techniques like x-ray diffraction or differential scanning calorimetry to offer a comprehensive view of the structure and phase formation not only in metallic glasses [26,29,[38][39][40] but also in many Fe-containing alloys [41][42][43]. In the present paper, FeCoSiB(Nb,Zr,Mo) metallic glasses have been produced in ribbon shape in order to study their amorphous structure and their crystallization by means of Transmission Mössbauer Spectroscopy (TMS) and shed some light on the effects of the different elements (Nb, Zr and Mo) on this Fe-based metallic glass.…”

Two-step combustion synthesis of nanocrystalline Zn1-xMnxFe2O4 (0<x<1) spinel ferrites with linear tuning of magnetic parameters

“…In this regard, the search for modified multistage methods of solution combustion with a wider set of controlled synthesis parameters, due to which it is possible to obtain pure multicomponent phases with small particle size, becomes especially urgent. One of these methods is the method of thermal treatment of X-ray amorphous products of solution combustion, within which the initial powder is synthesized with a significant excess or shortage of fuel and is thermally treated in an air atmosphere at temperatures from 500 to 800 • C. This original technique was first applied by the authors of this work for the synthesis of holmium and europium orthoferrites [26,27]. Nevertheless, the question of whether it can be used to obtain multicomponent spinel ferrites remains unanswered.…”
