The different magnetic phases of the intermetallic compound Nd5Ge3 are studied in terms of the specific heat, in a broad range of temperatures (350 mK–140 K) and magnetic fields (up to 40 kOe). The expected T3 and T 3 / 2 terms are not found in the

The minimization of Fisher’s information (MFI) approach of Frieden et al. [Phys. Rev. E 60, 48 (1999)] is applied to the study of size distributions in social groups on the basis of a recently established analogy between scale invariant systems and

For the first time, the morphology and dynamics of spin avalanches in Mn12-Acetate crystals using magneto-optical imaging has been explored. We observe an inhomogeneous relaxation of the magnetization, the spins reversing first at one edge of the cry
