I don't know about affecting the decay RATE as such,
but a powerful technique for investigating magnetic
critical point behavior is to dope the sample with
an isotope that decays via a pair of oppositely
directed gammas, and put the sample in an aligning
magnetic field with gamma detectors around the setup.
By studying the gamma-gamma correlations one can
infer the magnetic field near the probe nuclei.
(This technique is called "Perturbed Angular
Correlation"; it was a specialty of CLark University
not very many years ago.)  Temperature effects are
quite evident in this experiment, so temperature can
have detectable effects on nuclear decay.
