Observation of a new field-induced phase transition and its concomitant quantum critical fluctuations in CeCo(InZn)
M. Yokoyama, H. Mashiko, R. Otaka +10
We demonstrate a close connection between observed field-induced antiferromagnetic (AFM) order and quantum critical fluctuation (QCF) in the Zn7%-doped heavy-fermion superconductor…
Novel Pauli-paramagnetic quantum phase in a Mott insulator
D. Watanabe, M. Yamashita, S. Tonegawa +9
In Mott insulators, the strong electron-electron Coulomb repulsion prevents metallicity and charge excitations are gapped. In dimensions greater than one, their spins are usually o…
Determination of exchange energies in the sawtooth spin ring {Mo75V20} by ESR
Yugo Oshima, Hiroyuki Nojiri, Jürgen Schnack +2
The magnetism of the polyoxometalate cluster {Mo75V20}, containing a sawtooth ring of 10 corner-sharing triangles located on the equator of the barrel-shaped molecule, has remained…
Heat capacity uncovers physics of a frustrated spin tube
N. B. Ivanov, J. Schnack, R. Schnalle +6
We report on refined experimental results concerning the low-temperature specific heat of the frustrated spin tube material [(CuCl2tachH)3Cl]Cl2. This substance turns out to be an…
Magnetic field-induced phase transitions in a weakly coupled s = 1/2 quantum spin dimer system BaCrO
M. Kofu, H. Ueda, H. Nojiri +8
By using bulk magnetization, electron spin resonance (ESR), heat capacity, and neutron scattering techniques, we characterize the thermodynamic and quantum phase diagrams of Ba…
EMR Measurements of Field-Induced Superconductor lamda-(BETS)2FexGa1-xCl4
Y. Oshima, E. Jobiliong, J. S. Brooks +6
We have performed high-field Electron Magnetic Resonance (EMR) measurements of lamda-(BETS)2FexGa1-xCl4 to clarify the role of Pi- and d-electrons in the paramagnetic (PM) and fiel…
