Fig. 2: Comprehensive analysis of the NEMAD database.
From: The northeast materials database for magnetic materials

Histogram display the distribution and frequencies of the (a) Curie and (b) Néel temperatures across the database. c Bar chart represents the frequency of each element present in the database, highlighting the most common elements in magnetic materials. Only elements with a frequency greater than 300 are included. d Pie chart categorizes materials into binary, ternary, quaternary, quinary, and higher-order compounds, depicting their relative proportions within the database.
