Various mechanisms of electrical generation of spin polarization in nonmagnetic materials have been a subject of broad interest for their underlying physics and device potential in spintronics. One such scheme is chirality-induced spin selectivity (C

We combined scanning tunneling microscopy and locally resolved magnetic stray field measurements on the ferromagnetic semimetal EuB_{6}, which exhibits a complex ferromagnetic order and a colossal magnetoresistance effect. In a zero magnetic field, s

Combining self-catalyzed vapor-liquid-solid growth of GaAs nanowires and low-temperature molecular-beam epitaxy of (Ga,Mn)As, we successfully synthesized all zinc-blende (ZB) GaAs/(Ga,Mn)As core-shell nanowires on Si(111) substrates. The ZB GaAs nano

We demonstrate by magneto-transport measurements that a Curie temperature as high as 200 K can be obtained in nanostructures of (Ga,Mn)As. Heavily Mn-doped (Ga,Mn)As films were patterned into nanowires and then subject to low-temperature annealing. R

In the case of III–V dilute magnetic semiconductors (DMSs), the holes from Mn doping are known to mediate the ferromagnetic interaction. We firstly demonstrated the organic molecular manipulation of the magnetism of (Ga,Mn)As. Mn-doped GaAs thin fi

This paper reports on a study of the resistivity and Hall effect of the ferromagnetic pyrochlore $\mathrm{L}{\mathrm{u}}_{2}{\mathrm{V}}_{2}{\mathrm{O}}_{7}$. The temperature dependence of the resistivity of single crystalline $\mathrm{L}{\mathrm{u}}

In the case of III-V dilute magnetic semiconductors (DMS), the holes from Mn doping are known to mediate the ferromagnetic interaction among the Mn ions. Through modulation of the hole density, electrostatic gating has been shown to significantly alt

We present systematic studies of the excess low-frequency noise in GaAs/AlxGa1−xAs heterostructure 2DES Hall devices. We studied structures of various sizes made from different wafer materials. In larger samples a significant suppression of the 1/f
