Magnetic excitation spectra of the Kondo semimetal CeNiSn have been studied by neutron scattering under hydrostatic pressure up to 11 kbar. The inelastic peak at ℏω = 4 meV has been observed at the ambient pressure below Tcoh = 20 K and is regarded as a dynarmc antiferromagnetic correlation. As pressure is applied, the 4 meV peak shifts to a higher energy region and becomes weak. Since the pseudogap is known to be suppressed under high pressure, this result strongly suggests that the antiferromagnetic correlation is closely related to pseudogap formation.
