Uniaxial negative thermal expansion in a weak-itinerant-ferromagnetic phase of CoZrH
Yuto Watanabe, Kota Suzuki, Takayoshi Katase +3
We discovered unique uniaxial negative thermal expansion (NTE) behavior for a weak-itinerant-ferromagnetic phase of CoZrH. CoZr is known as a superconductor ex…

High entropy effect on thermoelectric properties of nonequilibrium cubic phase of AgBiSe2-2xSxTex with x = 0-0.6
Asato Seshita, Aichi Yamashita, Takayoshi Katase +1
Silver bismuth diselenide (AgBiSe2) has much attention as an efficient thermoelectric material due to its low thermal conductivity. However, AgBiSe2 exhibits multiple crystal struc…
