TL;DR: In this article, the results of magnetic relaxation experiments are shown to agree with theoretical predictions of quantum tunneling of the magnetization, and the authors emphasize the study of low temperature relaxation in ferromagnetic nanoparticles, layers, and multilayers (including domain wall junctions).

Quantum tunnelling in magnetic particles, layers and multilayers

TL;DR: In this paper, an analogy with Josephson junction was made for the case of the sandwiches (domain wall junction) and the role of dissipation was discussed, in terms of a crossover between a thermal regime, in which the irreversible rotation of the magnetization is thermally activated, and a quantum regime in which it proceeds by quantum tunnelling.
