Arising from P. N. Hai, S. Ohya, M. Tanaka, S. E. Barnes & S. Maekawa. Nature458, 489–492 (2009)10.1038/nature07879Magnetic tunnel junctions can produce large magnetoresistance effects that are of use in a variety of applications. Hai et al.1 recently published a very interesting paper in which the application of a large static magnetic field to a tunnel junction containing superparamagnetic MnAs nanoparticles resulted in the generation of an electromotive force. The authors attributed this phenomenon to a conversion of the nanoparticles’ magnetic energy to electrical energy by way of quantum tunnelling. Here I point out that the electrical energy output measured by Hai et al.1 was more than 1,000 times greater than the maximum amount of magnetic energy that could be induced in their MnAs nanoparticles by the applied magnetic field. Therefore the induced magnetic energy cannot be the source for the observed electromotive force, as was asserted by Hai et al.1.
