被引用回数：2 パーセンタイル：25.65(Physics, Multidisciplinary)Magnetic properties of TbSb are reported. Unlike previous investigations on a polycrystal showing multiple phase transitions, the present single crystal sample shows a single transition 133 K. It is also shown that the magnetic hysteresis increases at low temperatures.

被引用回数：18 パーセンタイル：73.31(Chemistry, Physical)Low-energy electronic structures of CeSb which shows multiple phase transitions known as devil's staircase were examined by combination of laser angle-resolved photoemission, Raman and neutron scattering spectroscopies. A new type of electron-boson coupling between the mobile electrons and quadrupole CEF-excitations of the 4f orbitals was found. The coupling is exceedingly strong and exhibits anomalous step-like enhancement during the devil's staircase transition, unveiling a new type of quasiparticle, named multipole polaron.
