Current is modulated through interactions with this quantity in a device proposed by Supriyo Datta and Biswajit Das (15[1])that is analogous to an electro-optic modulator. The torque induced by the transfer of this quantity (15[2])can be used to write cells in one technology’s “racetrack” form. (-5[1])This quantity accumulates when running electrical current through a 2D material in the Rashba–Edelstein effect. Due to the rarity of scattering events that change this quantity, resistance decreases sharply when a field is applied in an effect abbreviated (*) GMR. This quantity’s namesake (-5[3])valves are used to build transistors (10[1])and memory devices in a field whose name is a portmanteau of this quantity and “electronics.” (-5[1])This quantity (10[1])has a value of one or minus (10[1])one on each site in the (10[1])Ising model. For 10 points, an electron’s magnetic moment arises from what intrinsic quantity? (10[1])■END■ (10[3]0[1])
