Macroscopic quantum tunneling of magnetization explored by quantum-first-order reversal curves (QFORC)
Fanny Béron, Miguel A. Novak, Maria G. F. Vaz +4
A novel method to study the fundamental problem of quantum double well potential systems that display magnetic hysteresis is proposed. The method, coined quantum-first-order revers…
Fast Switching of Bistable Magnetic Nanowires Through Collective Spin Reversal
A. Vindigni, A. Rettori, L. Bogani +4
The use of magnetic nanowires as memory units is made possible by the exponential divergence of the characteristic time for magnetization reversal at low temperature, but the slow…
Finite-Size effects in "Single Chain Magnets": an experimental and theoretical study
L. Bogani, A. Caneschi, M. Fedi +7
The problem of finite size effects in s=1/2 Ising systems showing slow dynamics of the magnetization is investigated introducing diamagnetic impurities in a Co-radical chain…
Temperature dependence of the coercive field in single-domain particle systems
W. C. Nunes, W. S. D. Folly, J. P. Sinnecker +1
The magnetic properties of Cu97Co3 and Cu90Co10 granular alloys were measured over a wide temperature range (2 to 300K). The measurements show an unusual temperature dependence of…
The role of the alloy structure in the magnetic behavior of granular systems
C. S. M. Bastos, M. Bahiana, W. C. Nunes +4
The effect of grain size, easy magnetization axis and anisotropy constant distributions in the irreversible magnetic behavior of granular alloys is considered. A simulated granular…
Glauber slow dynamics of the magnetization in a molecular Ising chain
A. Caneschi, D. Gatteschi, N. Lalioti +7
The slow dynamics (10^-6 s - 10^4 s) of the magnetization in the paramagnetic phase, predicted by Glauber for 1d Ising ferromagnets, has been observed with ac susceptibility and SQ…
