概要

• 論文の詳細を見る

• We have studied the origin of the anomalous peak structure of resistivity of the low-carrier system CeSb appeared around the antiferromagnetic transition temperature T_N under high pressures by means of simultaneous measurement of lattice parameter by X-ray diffraction and resistivity together with neutron diffraction technique. It was found that there is a strong relationship between the unusual decrease of lattice parameter and the unusual increase of resistance below T_N under high pressure. Both of these phenomena can be explained by the appearance of Γ_8-like magnetic state of Ce^<3+> ion below T_N.
