  The temperature dependence of the chirality-induced spin selectivity (CISS)
effect can be used to discriminate between different theoretical proposals for
the mechanism of the CISS effect. Here we briefly review key experimental
results and discuss the effect of temperature in different models for the CISS
effect. We then focus on the recently suggested spinterface mechanism and
describe the different possible effects temperature can have within this model.
Finally, we analyze in detail recent experimental results from Qian, et.al.,
(Nature, 606, 902-908 (2022)) and demonstrate that, opposite to the original
interpretation by the authors, these data indicate that the CISS effect
increases with decreasing temperature. Finally, we show how the spinterface
model can accurately reproduce these experimental results.
