The ratio of the transition temperature to applied pressure related to the secondary Landau coefficient at TC for selected La-Fe-Si IEM alloys: La1.2Ce0.8Fe11Si2H1.86 (this work), LaFe11.33Co0.47Si1.228, LaFe11.74Mn0.06Si1.225, LaFe11.44Si1.5643, LaFe11.4Si1.639, LaFe11.57Si1.4344, LaFe10.95Co0.95Si1.145, and La0.7Ce0.3Fe11.44Si1.56H34. BTc is calculated from the magnetization curve at TC using the Landau expansion theory.
