a The white, colorful and black areas show the Ferrimagnetic (FiM) insulator, magnetic nodal-line semiconductor (MNLS) and FiM metal phases of the FiM Tc3(Si1-αGeα)2(Te1-βSβ)6 in the α-β plane, respectively. The color bar indicates band gaps of the insulating phase of the magnetic nodal-line semiconductors. b The correlation between TC and band gaps when the magnetizations of selected FiM Tc3(Si1-αGeα)2(Te1-βSβ)6 are long the a-axis. The red stars highlight near room-temperature magnetic semiconductors with reasonably large band gaps. c–h same as (a, b) but for Tc3(Si1-αGeα)2(Te1-βSeβ)6, Tc3(Si1-αSnα)2(Te1-βSβ)6, and Tc3(Si1-αSnα)2(Te1-βSeβ)6, respectively.
