Spin selectivity through chiral polyalanine monolayers on semiconductors
Tianhan Liu, Xiaolei Wang, Hailong Wang +11
Electrical generation of polarized spins in nonmagnetic materials is of great interest for the underlying physics and device potential. One such mechanism is chirality-induced spin…
Lattice strain accompanying the colossal magnetoresistance effect in EuB
Rudra Sekhar Manna, Pintu Das, Mariano de Souza +4
The coupling of magnetic and electronic degrees of freedom to the crystal lattice in the ferromagnetic semimetal EuB, which exhibits a complex ferromagnetic order and a colossa…
Bias current dependence of the spin lifetime in insulating AlGaAs
Jennifer Misuraca, Joon-Il Kim, Jun Lu +6
The spin lifetime and Hanle signal amplitude dependence on bias current has been investigated in insulating AlGaAs:Si using a three-terminal Hanle effect geometry.…
Spin transport and accumulation in the persistent photoconductor AlGaAs
Jennifer Misuraca, Joon-Il Kim, Jun Lu +6
Electrical spin transport and accumulation have been measured in highly Si doped Al0.3Ga0.7As utilizing a lateral spin transport device. Persistent photoconductivity allows for the…
Signatures of electronic phase separation in the Hall effect of anisotropically strained La0.67Ca0.33MnO3 films
Liuqi Yu, Lingfei Wang, Xiaohang Zhang +4
Systematic transport measurements have been performed on a series of La0.67Ca0.33MnO3 (LCMO) thin films with varying degrees of anisotropic strain. The strain is induced via epitax…
Magnetically-driven electronic phase separation in the semimetallic ferromagnet EuB
