Magnetic Field versus Temperature Phase Diagram of the Spin-1/2 Alternating Chain Compound F5PNN
Yasuo Yoshida, Tatsuya Kawae, Yuko Hosokoshi +5
We have measured the specific heat of the S = 1/2 alternating Heisenberg antiferromagnetic chain compound pentafluorophenyl nitronyl nitroxide in magnetic fields using a single cry…
Specific Heat Study on a Novel Spin-Gapped System : (CH_3)_2NH_2CuCl_3
Yasuo Yoshida, Osamu Wada, Yuji Inagaki +5
Specific heat measurements down to 120mK have been performed on a quasi-one-dimensional spin-gapped system (CH)NHCuCl in a magnetic field up to 8 T. This co…
Pressure-induced valence change in the rare earth metals:The case of Praseodymium
Naoyuki Tateiwa, Akitoshi Nakagawa, Kazuhiko Fujio +2
The rare earth metal praseodymium (Pr) transforms from the d-fcc crystal structure (Pr-III) to {}-U one (Pr-IV) at 20 GPa with a large volume collapse ( = 0.16), whi…
Specific Heat Study of an S=1/2 Alternating Heisenberg Chain System F_5PNN Under Magnetic Field
Y. Yoshida, N. Tateiwa, M. Mito +4
We have measured the specific heat of an S=1/2 antiferromagnetic alternating Heisenberg chain pentafulorophenyl nitronyl nitroxide under magnetic fields up to H>H_C2. This compound…
Non-Fermi Liquid Behavior in Dilute Quadrupolar System PrLaPb with 0.05
Tatsuya Kawae, Tatsuharu Yamamoto, Kenji Yurue +3
We have studied the low-temperature properties of PrLaPb with non-Kramers quadrupolar moments of the crystal-electric-field ground state, for a wide con…
