Unconventional superconductivity in bulk materials under ambient pressure is extremely rare among the 3d transition metal compounds outside layered cuprates and iron-based family. It predominantly linked to highly anisotropic electronic properties quasi-two-dimensional (2D) Fermi surfaces. To date, only known example of a Co-based exotic superconductor hydrated cobaltate, NaxCoO2·yH2O, its realized vicinity spin-1/2 Mott state. However, nature these still subject intense debate, therefore,...
Recent theoretical calculations have shown that ${\mathrm{Mn}}_{3}{\mathrm{Sn}}_{2}$, a well-known magnetocaloric material with multiple magnetic transitions, possesses both nodal lines and surfaces in its electronic structures, making it an excellent platform for studying anomalous transport properties topological candidates. In this work, we performed comprehensive electrical, thermal, thermoelectric measurements on ${\mathrm{Mn}}_{3}{\mathrm{Sn}}_{2}$ single crystals. The electrical...
Abstract Magnetoresistance (MR) stands as a pivotal transport phenomenon within the realm of condensed matter physics. In recent years, materials exhibiting extremely large unsaturated magnetoresistance (XMR), which are often potential topological materials, have garnered significant attention. this study, we synthesized single crystal ZrBi 2 and performed electrical specific heat measurements on them. The resistivity displays metallic behavior with high residual resistance ratio (RRR)....
Finding promising materials that show large thermoelectricity at low temperatures is crucial for low-temperature refrigeration applications. Here, we report a significantly thermoelectric power factor (PF) up to 50 μW cm−1 K−2 an extremely temperature of ∼8 K in quasi-one-dimensional (Q1D) antiferromagnet KMn6Bi5, which highly electrical conductivity and dramatic enhancement Seebeck coefficient may favor its occurrence. In addition, giant Nernst signal has also been detected with maximum...
We synthesize high-quality single crystal of CeGaSi by a Ga self-flux method and investigate its physical properties through magnetic susceptibility, specific heat electrical resistivity measurements as well high pressure effect. Magnetic reveal that an antiferromagnetic order develops below T m ∼ 10.4 K with moments orientated in the ab plane. The enhanced electronic coefficient negative logarithmic slope indicate title compound belongs to family Kondo system heavy fermion ground states....
The oxyselenide $\mathrm{K}{\mathrm{V}}_{2}\mathrm{S}{\mathrm{e}}_{2}\mathrm{O}$, featuring an anti-${\mathrm{K}}_{2}\mathrm{Ni}{\mathrm{F}}_{4}$-type layered structure, was successfully synthesized using a self-flux method. Comprehensive structural, electrical, and heat transport, as well magnetism measurements, were performed on both single crystals polycrystals. At 105 K, density-wave (DW)-like anomalous transition is revealed in temperature-dependent resistivity Hall coefficient,...
Mn 3 Sn 2 has been proposed as an ideal material for magnetic refrigeration. It undergoes two successive ferromagnetic transitions ( T C1 = 262 K and C2 227 K) one antiferromagnetic transition N 192 K). Herein we report, the first time, preparation of single crystals from Bi flux. The resultant anisotropic properties magnetocaloric effect are investigated along three principal crystallographic directions crystal. Significant anisotropy susceptibility multiple field-induced metamagnetic were...
