Abstract
Abstract Over the last decade, the construction and analysis of spintronic devices have been explored. This mini-review focuses on the basic spintronic phenomena such as giant magnetoresistance, tunnel magnetoresistance, spin transfer torque, spin Hall effect, spin Seebeck effect and BGKC (Bruno – Gnanasekar – Karunakaran – Chandramohan) observation. The mechanism of spin-orbit interaction is theoretically discussed. The in-plane wave vector, magnetic field, bias voltage and the delta potential are influenced on spin-polarized transport in heterostructures. The comparison between the role of Dresselhaus and Rashba spin-orbit interaction in the heterostructure is investigated. The principle of spintronic devices (sensors, magnetic random access memory, unipolar spin diode, spin photodiode, spin LED, spin solar cell, spin FET) and spintronic instruments (spin SEM, spin STM) are also explained.
