## 4 Analytical Discussion
### Publications Trends and Country Performance  
From the available statistics in this new bibliometric database, Figure 3 displays the total number of papers per year in the YIG field over the last ten years. As shown in Figure 3, the number of papers published has fluctuated throughout the past ten years. The maximum number of publications occurred in 2015. After 2016, fewer papers were published. Within 2021 and 2022, no citations for top cited papers have been documented. This study examines the recently published papers with the highest citation counts. Articles published in the past often receive more citations than those that were more recently published. This is apparent from Table 1, where the first top paper (13) was published in 2015 and the next six were published before 2015. Figure 1 illustrates that in the last ten years (2012-2022), the number of published papers has increased the most compared to the preceding year (1961-2011). This fact indicates that YIG research is experiencing \begin{table}
