Pressure-Induced Reentrant Oblique Antiferromagnetic Phase in Spin Dimer System TlCuCl_3 (2008)

Yamada, Fumiko, Ishii, Yasuyuki, Suzuki, Takao, Matsuzaki, Teiichiro, Tanaka, Hidekazu

Magnetization measurements under a hydrostatic pressure of P = 1.4 GPa were performed on the coupled spin dimer system TlCuCl_3, which exhibits a pressure-induced quantum phase transition from a...

Magnetic field-induced one-magnon Raman scattering in the magnon Bose-Einstein condensation phase of TlCuCl$_{3}$ (2008)

Kuroe, Haruhiko, Kusakabe, Kouhei, Oosawa, Akira, Sekine, Tomoyuki, Yamada, Fumiko, Tanaka, Hidekazu, ...

We report the observation of the $A_{\rm g}$-symmetric one-magnon Raman peak in the magnon Bose-Einstein condensation phase of TlCuCl$_{3}$. Its Raman shift traces the one-magnon energy at the...

Magnetic-Field Induced Bose-Einstein Condensation of Magnons and Critical Behavior in Interacting Spin Dimer System TlCuCl$_3$ (2007)

Yamada, Fumiko, Ono, Toshio, Tanaka, Hidekazu, Misguich, Gregoire, Oshikawa, Masaki, Sakakibara, Toshiro

Magnetization measurements were performed to investigate the critical behavior of the field-induced magnetic ordering in gapped spin system TlCuCl$_3$. The critical density of the magnons was...

The effect of randomness on the quantum spin system Tl$_{1-x}$K$_x$CuCl$_3$ with ${\boldmath $x$}$ = 0.44 studied by the Zero-field Muon-Spin-Relaxation (ZF-$\mu$SR) method (2007)

Suzuki, Takao, Yamada, Fumiko, Watanabe, Isao, Goto, Takayuki, Oosawa, Akira, Tanaka, Hidekazu

Zero-field muon-spin-relaxation (ZF-{\boldmath $\mu$}SR) measurements were carried out down to 80 mK on the randomness bond system Tl$_{1-x}$K$_x$CuCl$_3$ with $x$ = 0.44. Time spectra are well...

Purification and Characterization of a Proteinase from Pineapple Fruit, Fruit Bromelain FA2 (1976)

YAMADA, Fumiko, TAKAHASHI, Noriko, MURACHI, Takashi

Fruit bromelain FA2, the main proteinase component of the juice of pineapple fruit, has been purified and characterized. 1.Efficient extraction of this enzyme from the crude material was possible...
