摘要

•We report the introduction of Ag in Mn3Ga1-xAgxN can effectively tune the coefficient of NTE for the first time.•The substitution of Ag in Mn3Ga1-xAgxN results in the magnetic evolution from antiferromagnetic (AFM) to ferrimagnetic (FIM) with increasing Ag content.•The temperature coefficient of resistivity (TCR) can be tuned by Ag substitution in Mn3Ga1-xAgxN.
