Irradiation-induced confinement in a quasi-one-dimensional metal (2007)

Enayati-Rad, A., Narduzzo, A., Rullier-Albenque, F., Horii, S., Hussey, N. E.

The anisotropic resistivity of PrBa$_2$Cu$_4$O$_8$ has been measured as a function of electron irradiation fluence. Localization effects are observed for extremely small amounts of disorder...

Possible co-existence of local itinerancy and global localization in a quasi-one-dimensional conductor (2007)

Horii, S., Hussey, N. E.

In the chain compound PrBa$_2$Cu$_4$O$_8$ localization appears simultaneously with a dimensional crossover in the electronic ground state when the scattering rate in the chains exceeds the hopping...

Fragile three-dimensionality in the quasi-one-dimensional cuprate PrBa_2Cu_4O_8 (2007)

Narduzzo, A., Enayati-Rad, A., Heard, P. J., Kearns, S. L., Horii, S., Balakirev, F. F., ...

In this article we report on the experimental realization of dimensional crossover phenomena in the chain compound PrBa$_2$Cu$_4$O$_8$ using temperature, high magnetic fields and disorder as...

Universal relationship between crystallinity and irreversibility field of MgB2 (2005)

Yamamoto, A., Shimoyama, J., Ueda, S., Katsura, Y., Iwayama, I., Horii, S., ...

The relationship between irreversibility field, Hirr, and crystallinity of MgB2 bulks including carbon substituted samples was studied. The Hirr was found to increase with an increase of FWHM of MgB2...

Charge Freezing in Zig-zag Chain Cuprates PrBa2Cu4O8 Observed by Cu Nuclear Quadrupole Resonance (2002)

Fujiyama, S., Takigawa, M., Horii, S.

We report nuclear quadrupole resonance (NQR) studies on the chain Cu sites of PrBa$_{2}$Cu$_{4}$O$_{8}$, a quasi-one-dimensional conductor with a nearly quarter-filled band. The nuclear spin-lattice...

Spin dynamics and antiferromagnetic order in PrBa2Cu4O8 studied by Cu nuclear respnance (2002)

Fujiyama, S., Takigawa, M., Suzuki, T., Yamada, N., Horii, S., Yamada, Y.

Results of the nuclear resonance experiments for the planar Cu sites in PrBa2Cu4O8 are presented. The NMR spectrum at 1.5 K in zero magnetic field revealed an internal field of 6.1 T, providing...

Angle-resolved photoemission study of insulating and metallic Cu-O chains in PrBa$_2$Cu$_3$O$_7$ and PrBa$_2$Cu$_4$O$_8$ (2000)

Mizokawa, T., Kim, C., Ino, A., Yoshida, T., Fujimori, A., ...

We compare the angle-resolved photoemission spectra of the hole-doped Cu-O chains in PrBa$_2$Cu$_3$O$_7$ (Pr123) and in PrBa$_2$Cu$_4$O$_8$ (Pr124). While, in Pr123, a dispersive feature from the...
