EuZn$_2$P$_2$ was reported to be an insulating antiferromagnet with $T_\mathrm{N}$ of 23.5 K. In this study, single crystals exhibiting metallic behavior and a ferromagnetic order 72 K ($T_\mathrm{C}$) are successfully synthesized via salt flux method. The presence hole carriers induced by the Eu vacancies in lattice is found crucial for drastic changes magnetism electrical transport. mediate interlayer interaction, coupling strength directly related $T_\mathrm{C}$, as evidenced linear...
Materials that exhibit strongly coupled magnetic order and electronic properties are crucial for both fundamental research technological applications. However, finding a material not only shows remarkable magnetoresistive responses but also has an easily tunable ground state remains challenge. Here, we report successful manipulation of the transport ${\mathrm{EuCd}}_{2}{\mathrm{P}}_{2}$, which is transformed from A-type antiferromagnet...
We report the physical properties of ThRu 3 Si 2 featured with distorted Ru kagome lattice. The combined experiments resistivity, magnetization and specific heat reveal bulk superconductivity T c = 3.8 K. jump calculated electron–phonon coupling indicate a moderate coupled BCS superconductor. In comparison LaRu , electronic structure in shows an electron-doping effect electron filling lifted from 100 meV below flat bands to 300 above it. This explains lower superconducting transition...
We report the crystal growth, magnetoresistance (MR) with low and high magnetic field applied along crystallographic c axis, quantum Shubnikov–de Haas (SdH) de Haas–van Alphen (dHvA) oscillations of quasi-one-dimensional ternary telluride TaCo2Te2. The field-dependent MR at 2 K under up to 9 T follows a ρa(B)∼B1.56 relation, which slightly differs from ρa(B)∼B1.79 relation 58.9 without any signature saturation. SdH reveal two fundamental oscillation frequencies Fα=63.4 Fβ=158.5 T, second-...
Exploration of new superconductors in multicomponent complex systems remains challenging. Among superconductors, those containing distinct superconducting layers are quite rare. In this work, based on the block-layer model together with formation energy calculations, we have designed and successfully synthesized a quinary intermetallic compound, Th2Mo2Ir2Si4C. The material crystallizes an intergrowth structure alternate stacking ThMo2Si2C ThIr2Si2 block along crystallographic c axis....

The interactions between electrons and antiferromagnetic magnons (AFMMs) are important for a large class of correlated materials. For example, they the most plausible pairing glues in high-temperature superconductors, such as cuprates iron pnictides. However, unlike electron-phonon (EPIs), clear-cut observations regarding how electron-AFMM (EAIs) affect band structure still lacking. Consequently, critical information on EAIs, its strength doping dependence, remains elusive. Here we directly...
Abstract We report the effect of carbon doping in Ti‐stabilized nonstoichiometric molybdenum diboride B 2 , which exhibits bulk superconductivity below T c = 7.0 K. It is found that maintains AlB ‐type phase with a uniform elemental distribution for x 0.12 and 0.16. The substitution boron leads to slight increase ‐axis, remarkable reduction formation planar defects along (100) crystallographic planes, shift 1 s peaks toward higher binding energies. Contrary however, no observed down 1.8 K...
Materials that exhibit strongly coupled magnetic order and electronic properties are crucial for both fundamental research technological applications. However, finding a material not only shows remarkable magnetoresistive responses but also has an easily tunable ground state remains challenge. Here, we report successful manipulation of the transport EuCd$_2$P$_2$, which is transformed from A-type antiferromagnet ($T_\mathrm{N}$ = 11 K) exhibiting colossal magnetoresistance into ferromagnet...
The antiferromagnetism in transition metal compounds is mostly mediated by the bridging anions through a so-called superexchange mechanism. However, materials like normal spinels $AB_2X_4$ with local moments only at $A$ site, such an anion-mediated needs to be modified. Here we report new spinel compound Co$_{1+x}$Ir$_{2-x}$S$_4$ ($x$ = 0.3). physical property measurements strongly suggest antiferromagnetic-like 292 K Co($A$) diamond sublattice. first-principle calculations reveal that...
