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...
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....
Magnetic topological materials have attracted much attention due to the interplay between magnetism and electronic band structure, which may not only generate new exotic quantum states but also bring great potential applications. Here, we present Seebeck Nernst effects in magnetic Weyl semimetal NdAlSi as a function of temperature field. We find that power factor reaches...
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,...
A method to distinguish the bulk and interface scenarios of fatigue in sol-gel derived Pb(Zr0.5Ti0.5)O3 (PZT) thin films on Pt LaNiO3 (LNO) substrates is proposed based asymmetric electric field driving capacitors. The “hard” “soft” failures polarization, which are typical for sputtering deposited PZT, respectively, realized Pt/PZT/Pt capacitors by changing asymmetricity pulses, indicating that plays an important role polarization breakdown. For Pt/PZT/LNO capacitors, it shown pinning...

We report a comprehensive study on layered-structure compound of NaZn 4 As 3 , which has been predicted to be an ideal topological semimetal (TSM) candidate. It is found that undergoes structural transformation from high temperature rhombohedral low monoclinic phase. The electric resistivity exhibits metal-to-insulator-like transition at around 100 K, and then develops plateau temperature, might related the protected topologically conducting surface states.
