DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Magneto-plumbite ferrites with hexagonal structures have revealed a higher dispersion frequency than NiCuZn ferrites, which can be used in high frequency applications. Among those ferrites, the Co2Y ferrite 2(BaO)．2(CoO)．6(Fe2O3) has good magnetic properties (such as permeability and quality factors) above 200MHz. However, the densification temperature of Co2Y ferrites always exceeds 1000oC and the initial permeability of low temperature fired Co2Y ferrites with glass addition is too low (μi = 2-4), which limit its application in multilayer chip inductors. Improved the densification at low temperatures can be achieved by adding glass flux. However, the glass addition often results in magnetic properties degradation due to the low-permeability additive dilution effect or the chemical reaction between the glass and ferrites to form a low-permeability phase. In this study, the magnetic properties of low temperature sintering Co2Y ferrite can be improved by adding nickel- copper- zinc (NiCuZn) ferrites, and investigated the effect of the addition of NiCuZn ferrites on the magnetic properties and microstructure of Co2Y.
  The results show that no second phase was observed for the Co2Y- NiCuZn ferrite composite sintering at 900°C and the densification temperature can not only be reduced to 850oC, but also can effectively enhance the initial permeability by adding trace addition of nickel-copper-zinc ferrites. The initial permeability increased with increasing the addition of the NiCuZn ferrite. When the NiCuZn ferrites addition was up to 20wt%, the initial permeability of 4-5 (1MHz- 1 GHz) could be obtained for the Co2Y- NiCuZn ferrite composite sintering at 900°C.
