Physical Review B, Dec. 2022, [Reviewed] - 〔Major achievements〕Direct measurement of the evolution of magnetism and superconductivity toward the quantum critical point
W. Higemoto; M. Yokoyama; T. U. Ito; T. Suzuki; S. Raymond; and Y. Yanase, Corresponding, Nontrivial quantum states can be realized in the vicinity of the quantum critical point (QCP) in many strongly correlated electron systems. In particular, an emergence of unconventional superconductivity around the QCP strongly suggests that the quantum critical fluctuations play a central role in the superconducting pairing mechanism. However, a clear signature of the direct coupling between the superconducting pairing states and the quantum criticality has not yet been elucidated by the microscopic probes. Herein, we present muon spin rotation/relaxation and neutron diffraction measurements in the superconducting dome of CeCo(In1 - xZnx)5. It was found that a magnetically ordered state develops at x≥ 0.03, coexisting with the superconductivity. The magnitude of the ordered magnetic moment is continuously reduced with decreasing x, and it disappears below x∼ 0.03, indicating a second-order phase transition and the presence of the QCP at this critical Zn concentration. Furthermore, the magnetic penetration depth diverges toward the QCP. These facts provide evidence for the intimate coupling between quantum criticality and Cooper pairing.

Physical Review B, Nov. 2016, [Reviewed] - 〔Major achievements〕Superconductivity and non-Fermi-liquid behavior in the heavy-fermion compound CeCo$_{1-x}$Ni$_x$In$_5$
Ryo Otaka; Makoto Yokoyama; Hiroaki Mashiko; Takeshi Hasegawa; Yusei Shimizu; Yoichi Ikeda; Kenichi Tenya; Shota Nakamura; Daichi Ueta; Hideki Yoshizawa; Toshiro Sakakibara, Corresponding, The effect of off-plane impurity on superconductivity and non-Fermi-liquid
(NFL) behavior in the layered heavy-fermion compound CeCo$_{1-x}$Ni$_x$In$_5$
is investigated by specific heat, magnetization, and electrical resistivity
measurements. These measurements reveal that the superconducting (SC)
transition temperature T$_c$ monotonically decreases from 2.3 K (x=0) to 0.8 K
(x=0.20) with increasing x, and then the SC order disappears above x=0.25. At
the same time, the Ni substitution yields the NFL behavior at zero field for
x=0.25, characterized by the -ln T divergence in specific heat divided by
temperature, C$_p$/T, and magnetic susceptibility, M/B. The NFL behavior in
magnetic fields for x=0.25 is quite similar to that seen at around the SC upper
critical field in pure CeCoIn$_5$, suggesting that both compounds are governed
by the same antiferromagnetic quantum criticality. The resemblance of the
doping effect on the SC order among Ni- , Sn-, and Pt-substituted CeCoIn5
supports the argument that the doped carriers are primarily responsible for the
breakdown of the SC order. The present investigation further reveals the
quantitative differences in the trends of the suppression of superconductivity
between Ce(Co,Ni)In$_5$ and the other alloys, such as the rates of decrease in
T$_c$, dT$_c$/dx, and specific heat jump at T$_c$, d($\Delta$C$_p$/T$_c$)/dx.
We suggest that the occupied positions of the doped ions play an important role
in the origin of these differences.

Physical Review B, 2015, [Reviewed] - 〔Major achievements〕Possible Evolution of Antiferromagnetism in Zn-Doped Heavy-Fermion Superconductor CeCoIn5
M. Yokoyama; K. Fujimura; S. Ishikawa; M. Kimura; T. Hasegawa; I. Kawasaki; K. Tenya; Y. Kono and T. Sakakibara, Lead, We have succeeded in growing single crystals of the heavy-fermion
superconductor CeCo(In1-xZnx)5 with x<=0.07. Measurements of specific heat,
electrical resistivity, dc magnetization and ac susceptibility revealed that
the superconducting (SC) transition temperature Tc decreases from 2.25 K (x=0)
to 1.8 K (x=0.05) by doping Zn into CeCoIn5. Furthermore, these measurements
indicate a development of a new ordered phase below T_o ~ 2.2 K for x=>0.05,
characterized by the reduced magnetization and electrical resistivity in the
ordered phase, and the enhancement of specific heat at T_o. This phase
transition can be also recognized by the shoulder-like anomaly seen at H_o ~ 55
kOe in the field variations of the magnetization at low temperatures, which is
clearly distinguished from the superconducting critical fields Hc2=49 kOe for
x=0.05 and 42 kOe for x=0.07. We suggest from these results that the
antiferromagnetic (AFM) order is generated by doping Zn, and the interplay
between the SC and AFM orders is realized in CeCo(In1-xZnx)5.
