Polarization analysis of terahertz emission from Bi-2212 cross-whisker intrinsic Josephson junction and its refractive index
Yoshito Saito, Istuhiro Kakeya, Yoshihiko Takano
Polarization analyses of the terahertz (THz) emission from BiSrCaCuO whisker crystals used for superconducting THz emitters were conducted. The THz emissi…
THz emission from a Bi2Sr2CaCu2O8+δ cross-whisker junction
Yoshito Saito, Shintaro Adachi, Ryo Matsumoto +7
Cuprate superconductor Bi2Sr2CaCu2O8+δ (BSCCO) has been a promising candidate of a coherent, continuous, and compact THz light source owing to its intrinsic Josephson junction insi…
Enhancement of giant refrigerant capacity in HoGdB alloys (0.1 x 0.4)
Pedro Baptista de Castro, Kensei Terashima, Takafumi D Yamamoto +8
Intending to optimize the giant magnetocaloric properties of HoB, we synthesized and magnetocalorically characterized HoGdB(0.1 x 0.4) alloy…
Effect of Dy substitution in the giant magnetocaloric properties of HoB
Pedro Baptista de Castro, Kensei Terashima, Takafumi D. Yamamoto +6
Recently, a massive magnetocaloric effect near the liquefaction temperature of hydrogen has been reported in the ferromagnetic material HoB. Here we investigate the effects o…
Machine Learning Guided Discovery of Gigantic Magnetocaloric Effect in HoB Near Hydrogen Liquefaction Temperature
Pedro Baptista de Castro, Kensei Terashima, Takafumi D Yamamoto +8
Magnetic refrigeration exploits the magnetocaloric effect which is the entropy change upon application and removal of magnetic fields in materials, providing an alternate path for…
Demonstration of Electric Double Layer Gating under High Pressure by the Development of Field-Effect Diamond Anvil Cell
Shintaro Adachi, Ryo Matsumoto, Sayaka Yamamoto +9
We have developed an approach to control the carrier density in various material under high pressure by the combination of an electric double layer transistor (EDLT) with a diamond…
