Integral Absorption of Microwave Power by Random-Anisotropy Magnets

E. M. Chudnovsky, D. A. Garanin

We study analytically and numerically on lattices containing spins, the integral absorption of microwaves by a random-anisotropy magnet, . It scales as $D^2_R/J…

Thermal fluctuations of the Josephson current in a ring of superconducting grains

D. A. Garanin, E. M. Chudnovsky

Thermal fluctuations of the Josephson current induced by the magnetic flux through a ring of superconducting grains are studied. When a half-fluxon is threading the ring, $…

Stability of Suspended Graphene under Casimir Force

E. M. Chudnovsky, R. Zarzuela

We consider graphene sheet suspended above a conducting surface. Treating graphene as an elastic membrane subjected to Casimir force, we study its stability against attachment to t…

Quantum decay of the persistent current in a Josephson junction ring

D. A. Garanin, E. M. Chudnovsky

We study the persistent current in a ring consisting of N >> 1 Josephson junctions threaded by the magnetic flux. When the dynamics of the ring is dominated by the capacitances of…

Resonant Spin Tunneling in Randomly Oriented Nanospheres of Mn Acetate

S. Lendinez, R. Zarzuela, J. Tejada +6

We report measurements and theoretical analysis of resonant spin tunneling in randomly oriented nanospheres of a molecular magnet. Amorphous nanospheres of Mn acetate have b…

Damping of a nanocantilever by paramagnetic spins

E. M. Chudnovsky, D. A. Garanin

We compute damping of mechanical oscillations of a cantilever that contains flipping paramagnetic spins. This kind of damping is mandated by the dynamics of the total angular momen…
