✦ Synopsis


We have studied an effect of pressure on the ferromagnetism of Ce 2 Ni 5 C 3 by ac susceptibility using a newly developed Palm cubic anvil cell up to 5.2 GPa. The ferromagnetic transition temperature of 2.3 K at ambient pressure is suppressed to zero at a critical pressure P ∼ 3.8 GPa. Instead, another magnetic phase appears above this pressure. This new magnetic phase is considered to be antiferromagnetic from the result of the magnetic field dependence of the ac susceptibility.
