Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>We analyse the spin relaxation length during vertical electron transport in spin light‐emitting diode devices at room temperature. We obtain a spin relaxation length of 27 nm in remanence. When a magnetic field is applied, spin relaxation is significantly reduced during transport to the active region of the device. This results in a nearly doubled spin relaxation length at 2T magnetic field strength.</p> </abstract>
