Correction to "synthesis of magnetic noble metal (nano)particles".

Langmuir 2011, 27 (12), 7783−7787. DOI: 10.1021/la105051v ■ INTRODUCTION Recently, some of us reported on the production of magnetic noble metal nanoparticles. It was claimed, that when noble metal nanoparticles were synthesized in a sufficiently strong magnetic field, they would acquire (ferro)magnetism. The obtained magnetism was reported to be equivalent to that of iron if present at about 2% of the total mass. This amount of iron was orders of magnitude larger than what was actually detected with the techniques used. We here report on new experimental results that were obtained while trying to enhance the yield of magnetic material.
