TY - JOUR T1 - A room-temperature ferrimagnet made of metallo-proteins? JF - bioRxiv DO - 10.1101/094607 SP - 094607 AU - Michael Winklhofer AU - Henrik Mouritsen Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/12/15/094607.abstract N2 - Qin et al. (A magnetic protein compass, Nature Materials 15, 217-226, 2016) claim that "MagR is the first known protein that carries an intrinsic magnetic moment at ambient temperature". We show here that the claim must, unfortunately, be fundamentally wrong. ER -
