Abstract

We have investigated the pressure effect on magnetic properties of a weak itinerant ferromagnet BaIrO3, using a Cu-Be piston-cylinder type pressure cell. Under external pressure the ferromagnetic transition temperature Tc decreases linearly with pressure at a large rate of dT c/dP ∼ -17 K/GPa. The critical exponent β up to 0.86 GPa indicates the anomalous value (β ∼ 0.9) and is nearly pressure-independent. Anomalous pressure effects on conductivity and magnetism suggest the existence of a nontrivial coupling among charge, spin and lattice in this compound.
