The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RESUMO

Manganese ferrite (MnFe2O4) as a magnetic material was greatly affected by several parameters formed during the synthesis process. One of the parameters necessary in the coprecipitation synthesis process is the pH concentration in the titration process. The pH variations can affect the magnetic properties of MnFe2O4, and it was very interesting to review the effect of pH on its magnetic properties of. Manganese ferrite was synthesized by using the coprecipitation method with pH being equal to 8, 10, and 12 and sintered at a temperature of 1000°C for 3 h. Manganese ferrite nanopowder that had been synthesized was analyzed by using XRD, SEM, and VSM. The characterization process was conducted with both sintered and unsintered manganese ferrite. The XRD results indicated that the unsintered sample at all values of pH was amorphous, while the sintered samples at all pH values showed that a single phase was formed in a lattice with dimensions 59.48 nm, 41.60 nm, and 29.72 nm for pH equal to 8, 10, and 12. The SEM testing showed that the structure of all samples was homogeneous. Although the bulk size of unsintered samples was smaller and more homogeneous than that of sintered samples, the results showed that all unsintered samples had similar values and superparamagnetic properties. However, unlike the sintered sample, which was much more homogeneous, there was transition from the superparamagnetic properties to paramagnetic properties at pH equal to 12. Thus, it was found that the higher the pH level, the smaller the crystallite size.
