Narrow Zero-Field Tunneling Resonance in Triclinic Mn Acetate Ribbons
I. Imaz, J. Espin, D. Maspoch +4
We report synthesis, structural characterization, and magnetic measurements of amorphous Mn-acetate ribbons with a triclinic short-range crystal order not previously seen in…
Enhanced spin tunneling in a molecular magnet mixed with a superconductor
J. Tejada, R. Zarzuela, A. García-Santiago +4
We report characterization and magnetic studies of mixtures of micrometer-size ribbons of Mn acetate and micrometer-size particles of YBaCuO superconductor. Extremely narrow…
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…
Josephson junction with a magnetic vortex
R. Zarzuela, E. M. Chudnovsky, J. Tejada
We have studied Josephson tunneling through a circularly polarized micron or submicron-size disk of a soft ferromagnetic material. Such a disk contains a vortex that exhibits rich…
Dissipative Macroscopic Quantum Tunneling in Type-I Superconductors
R. Zarzuela, E. M. Chudnovsky, J. Tejada
We study macroscopic quantum tunneling of interfaces separating normal and superconducting regions in type-I superconductors. Mathematical model is developed, that describes dissip…
Rotational Doppler Effect in Magnetic Resonance
S. Lendinez, E. M. Chudnovsky, J. Tejada
We compute the shift in the frequency of the spin resonance in a solid that rotates in the field of a circularly polarized electromagnetic wave. Electron spin resonance, nuclear ma…
