Impact of Controlled Magneto‐Structural Coupling in MnCoGe‐Based Compounds on the Design of Multifunctional Materials for Technological Advances

Advanced Science, EarlyView.
In this work, the authors systematically investigate how Ni substitution regulates the magneto‐structural coupling and their functional consequences in the MnCoGe‐based compounds. Geometric nonlinear theory analysis reveals that Ni modification change of magneto‐structural transition can alleviate the lattice incompatibility, thereby broadening the ...
