Pressure suppresses Mn antiferromagnetic order in CeMnSi at ~1.3 GPa, induces a new anomaly at ~97 K, and the compound exhibits negative thermal expansion below ~40 K at ambient pressure consistent with a heavy-fermion ground state.
This behavior reflects the dif- ference in energy scales between the high-temperature Mn-derived magnetism and the low-temperature Ce- 4 f 6 J

Pressure Effects on CeMnSi: Evolution of Ce 4f and Mn 3d Electronic States and Negative Thermal Expansion
Pressure suppresses Mn antiferromagnetic order in CeMnSi at ~1.3 GPa, induces a new anomaly at ~97 K, and the compound exhibits negative thermal expansion below ~40 K at ambient pressure consistent with a heavy-fermion ground state.
