81. The results of Awschalom et al. on ferritin molecules have been queried or criticised by a number of authors; questions have centered around the role of the dipolar coupling between molecules (Ref. 3 above); the experimental power absorption and lineshape, particularly in a field (see A. Garg, Phys. Rev. Lett. 70, C2198 (1993), and reply of D. D. Awschalom et al., ibid., C2199 (1993); or A. Garg, Phys. Rev. Lett. 71, 4241 (1993), and the associated Comment of D. D. Awschalom et al., ibid., C4276 (1993); or A. Garg, Science 272, 425 (1996), with the reply of D. D. Awschalom et al., ibid., 425 (1996)); the role of nuclear spins (see N. V. Prokof'ev and P. C. E. Stamp, Refs. 45-47, and Ref. 49 above), as well as A. Garg, Phys. Rev. Lett. 74, 1458 (1995)); and finally the claimed inconsistency with high-T blocking (see J. Tejada, Science 272, 424 (1996), and the reply by D. D. Awschalom et al., ibid., 425 (1996)). Note that in the later papers of Awschalom et al. it is found that the ferritin resonance frequency scales with the size of the Fe core roughly as one would expect from the coherent tunneling interpretation, which gives strong support to this explanation.

Note that in the later papers of Awschalom et al. it is found that the ferritin resonance frequency scales with the size of the Fe core roughly as one would expect from the coherent tunneling interpretation, which gives strong support to this explanation.
88. The results of Awschalom et al. on ferritin molecules have been queried or criticised by a number of authors; questions have centered around the role of the dipolar coupling between molecules (Ref. 3 above); the experimental power absorption and lineshape, particularly in a field (see A. Garg, Phys. Rev. Lett. 70, C2198 (1993), and reply of D. D. Awschalom et al., ibid., C2199 (1993); or A. Garg, Phys. Rev. Lett. 71, 4241 (1993), and the associated Comment of D. D. Awschalom et al., ibid., C4276 (1993); or A. Garg, Science 272, 425 (1996), with the reply of D. D. Awschalom et al., ibid., 425 (1996)); the role of nuclear spins (see N. V. Prokof'ev and P. C. E. Stamp, Refs. 45-47, and Ref. 49 above), as well as A. Garg, Phys. Rev. Lett. 74, 1458 (1995)); and finally the claimed inconsistency with high-T blocking (see J. Tejada, Science 272, 424 (1996), and the reply by D. D. Awschalom et al., ibid., 425 (1996)).
