Paramagnetic Meissner effect in YBa2Cu3O7: influence of AC magnetic field and magnetic relaxation

We have investigated the superconducting transition region in YBa2Cu3O7 single crystal showing the paramagnetic Meissner effect (PME). In the temperature region where the PME appears the sample reveals logarithmic relaxation of magn...

Unconventional spin relaxation involving localized vibrational modes in Ho single-atom magnets

We investigate the spin relaxation of Ho single atom magnets on MgO=Agð100Þ as a function of temperature and magnetic field. We find that the spin relaxation. This behavior contrasts with that of single molecule magnets and bulk
