Starting from the definition of Hall effect in Section 1, a brief summary of the reported theories related to the magnetic intermetallic compounds is presented in Section 2. The emphasis is to put the information obtainable from the Hall effect measu

Neutron scattering experiments have been carried out on the heavy fermion antiferromagnetic (AFM) superconductor CePt3Si with TN = 2.2 K and TSC = 0.75 K. We observed clear AFM Bragg reflections with Q0 = (001/2) below and above TSC, indicating micro

We report on measurements of the Knight shift K and spin–lattice relaxation rate λ of positive muons (μ+) implanted in cubic CeAg, a compound which is known to possess ferromagnetic ( K) and ferroquadrupolar (TQ = 15–16 K) order. The zero field

High resolution neutron scattering experiments have been carried out in order to study the interplay between magnetism and superconductivity in the heavy fermion superconductor ${\mathrm{UPd}}_{2}{\mathrm{Al}}_{3}$. We found direct evidence for a mag

In order to investigate the metamagnetic anomaly (MA) observed in several heavy-fermion compounds, field dependence of specific heat C(B) and magnetocaloric effect have been measured in the prototypical 4f-electron compound CeRu2Si2, and compared to

Bulk electronic structures of Pr-based filled skutterudites and their reference materials have been investigated by bulk-sensitive photoemission spectroscopy using soft and hard X-rays. For Pr 3 d – 4 f resonance, a strong intensity in the vicinity

We report the first successful results on the de Haas-van Alphen (dHvA) experiments of the superconducting LaFe 4 P 12 and the ferromagnetic NdFe 4 P 12 . Their Fermi surfaces are found to be similar except for the splitting of the dHvA branches for

We report pressure dependence of the Fermi surfaces (FSs) in CeRu 2 Si 2 below and above the metamagnetic transition field (H m ) . Below H m , the dHvA frequencies arising from hole FSs decrease by 20% on application of 6 kbar, while that from an el

We have studied the origin of the cooperative Jahn-Teller effect in PrCu 2 . We have determined the anisotropic phase diagram by measuring the thermal expansion and the magnetostriction in magnetic fields up to 15 T. The Jahn-Teller transition temper
