An experimental demonstration of room-temperature spin transport in n-type Germanium epilayers
Sergey Dushenko, Mariko Koike, Yuichiro Ando +3
We report the first experimental demonstration of room-temperature spin transport in n-type Ge epilayers grown on a Si(001) substrate. By utilizing spin pumping under ferromagnetic…
Dynamical Spin Injection into p-type Germanium at Room Temperature
Mariko Koike, Eiji Shikoh, Yuichiro Ando +4
We demonstrate dynamical spin injection into p-type germanium (Ge) at room temperature (RT) using spin pumping. The generated pure spin current is converted to a charge current by…
N=2 Supermultiplet of Currents and Anomalous Transformations in Supersymmetric Gauge Theory
H. Itoyama, M. Koike, H. Takashino
We examine some properties of supermultiplet consisting of the U(1)_{J} current, extended supercurrents, energy-momentum tensor and the central charge in N=2 supersymmetric Yang-Mi…
Multicritical Behavior of Matrix Model
H. Itoyama, M. Koike
We discuss multicritical behavior of matrix model, extending the recent work of ref. \cite{CIO} on a nonperturbative completion of the density of states function. For the odd…
