Implications of Tc variation in UBe13 for a possible Fulde-Ferrell-Larkin-Ovchinnikov phase
H. A. Radovan, R. J. Zieve, J. S. Kim +1
We measure the heat capacity of UBe13 with an unusually low Tc for a polycrystal. We find an upturn in the upper critical field Hc2(T) below about Tc/2, much as for higher-Tc sampl…
Changes in the surface electronic structure upon martensitic transformation in TiNi and TiPd
S. E. Kulkova, V. E. Egorushkin, J. S. Kim +2
The electronic structure of some low index surfaces for martensitic B19'-TiNi and B19-TiPd were investigated using the full-potential linearized augmented plane wave method. The al…
Heavy-ion irradiation of UBe13 superconductors
H. A. Radovan, E. Behne, R. J. Zieve +4
We irradiate the heavy fermion superconductors (U,Th)Be_13 with high-energy heavy ions. Damage from the ions affects both heat capacity and magnetization measurements, although muc…
Unusual T_c variation with hole concentration in Bi_2Sr_{2-x}La_xCuO_{6+δ}
Mu-Yong Choi, J. S. Kim
We have investigated the variation with the hole concentration in the La-doped Bi 2201 system, BiSrLaCuO. It is found that the Bi 2201 system does…
Thermopower of high-T_c cuprates
Mu-Yong Choi, J. S. Kim
We have studied the thermopower of La_2CuO_{4+z} and Nd_2CuO_{4-y} which undergo an antiferromagnetic transition near room temperature and Bi_2Sr_{2-x}La_xCuO_{6+z} for which a bro…
