Long-range order and spin-liquid states of polycrystalline TbTiO
T. Taniguchi, H. Kadowaki, H. Takatsu +11
Low-temperature states of polycrystalline samples of a frustrated pyrochlore oxide TbTiO have been investigated by specific heat, magnetic susceptibility, a…
Field evolution of quantum critical and heavy Fermi-liquid components in the magnetization of the mixed valence compound beta-YbAlB4
Yosuke Matsumoto, K. Kuga, Y. Karaki +5
We present the high-precision magnetization data of the valence fluctuating heavy fermion superconductor -YbAlB in a wide temperature range from 0.02 K to 320 K spanning fo…
Antiferromagnetic correlations in strongly valence fluctuating CeIrSn
Y. Shimura, A. Wörl, M. Sundermann +11
CeIrSn with a quasikagome Ce lattice in the hexagonal basal plane is a strongly valence fluctuating compound, as we confirm by hard x-ray photoelectron spectroscopy and inelastic n…
CeCu_2Ge_2: Challenging our Understanding of Quantum Criticality
B. Zeng, Q. R. Zhang, D. Rhodes +6
Here, we unveil evidence for a quantum phase-transition in CeCu_2Ge_2 which displays both an incommensurate spin-density wave (SDW) ground-state, and a strong renormalization of th…
Radio frequency single electron transmission spectroscopy of a semiconductor Si/SiGe quantum dot
I. Fattal, J. Van Damme, B. Raes +14
Rapid single shot spin readout is a key ingredient for fault tolerant quantum computing with spin qubits. An RF-SET (radio-frequency single electron transistor) is predominantly us…
Bulk Fermi-surface of the Weyl type-II semi-metallic candidate MoTe2
D. Rhodes, R. Schönemann, N. Aryal +15
The electronic structure of WTe and orthorhombic MoTe, are claimed to contain pairs of Weyl type-II points. A series of ARPES experiments claim a broad agreement with…
Observation of thermodynamics originating from a mixed-spin ferromagnetic chain
H. Yamaguchi, S. C. Furuya, S. Morota +6
We present a model compound that forms a mixed-spin ferromagnetic chain. Our material design, based on the organic radicals, affords a verdazyl-based complex (p-Py-V)2[Mn(hfac)2].…
Magnetic and structural quantum phase transitions in CeCu6-xAux are independent
K. Grube, L. Pintschovius, F. Weber +9
The heavy-fermion compound CeCuAu has become a model system for unconventional magnetic quantum criticality. For small Au concentrations , the compound…
Destruction of Kondo effect in cubic heavy fermion compound Ce3Pd20Si6
J. Custers, K. -A. Lorenzer, M. Müller +9
How ground states of quantum matter transform between one another reveals deep insights into the mechanisms stabilizing them. Correspondingly, quantum phase transitions are explore…
T/B scaling of magnetization in the mixed valent compound β-YbAlB4
Yosuke Matsumoto, S. Nakatsuji, K. Kuga +5
Here we provide the first clear evidence of Fermi-liquid breakdown in an intermediate valence system. We employ high precision magnetization measurements of the valence fluctuating…
