Observation of hydrostatic-pressure-modulated giant caloric effect and electronic topological transition
Jinying Yang, Xingchen Liu, Yibo Wang +12
Phase transition is a fundamental phenomenon in condensed matter physics, in which states of matter transform to each other with various critical behaviors under different conditio…
Evolution of structure, magnetism, and electronic/thermal-transports of Ti(Cr)-substituted Fe2CrV all-d-metal Heusler ferromagnets
Yiting Feng, Shen Zhang, Qingqi Zeng +9
All-d-metal full-Heusler alloys possess superior mechanical properties and high spin polarization, which would play an important role in spintronic applications. Despite this, thei…
Topological Nodal Chains and Transverse Transports in Ferromagnetic Centrosymmetric Semimetal FeIn2S4
Junyan Liu, Yibo Wang, Xuebin Dong +8
Nodal chain semimetals protected by nonsymmorphic symmetries are distinct from Dirac and Weyl semimetals, featuring unconventional topological surface states and resulting in anoma…
Generic Seebeck Effect From Spin Entropy
Peijie Sun, K. Ramesh Kumar, Meng Lyu +3
How magnetism affects the Seebeck effect is an important issue widely concerned in the thermoelectric community yet remaining elusive. Based on a thermodynamic analysis of spin deg…
Nonsaturating magnetoresistance, anomalous Hall effect, and magnetic quantum oscillations in ferromagnetic semimetal PrAlSi
Meng Lyu, Junsen Xiang, Zhenyu Mi +7
We report a comprehensive investigation of the structural, magnetic, transport and thermodynamic properties of a single crystal PrAlSi, in comparison to its nonmagnetic analogue La…
Large transverse thermoelectric figure of merit in a Dirac semimetal
Junsen Xiang, Sile Hu, Meng Lyu +6
Thermoelectric (TE) conversion in conducting materials is of eminent importance for providing renewable energy and solid-state cooling. Although traditionally, the Seebeck effect p…
