Slow magnetic relaxation and proton conduction in a highly ...

This work not only provides the first bifunctional HoIII complexes showing slow magnetic relaxation and proton-conducting behaviour but also a ...

EXPERIMENTAL REALISATION OF SINGLE-ATOM MAGNETS

Ho atoms possess a high magnetic moment in a magnetic field of 8.5 T and at 6 K. Surprisingly, hysteretic behaviour appears as the magnetisation is measured ...

Unconventional Spin Relaxation Involving Localized Vibrational ...

We investigate the spin relaxation of Ho single atom magnets on $\mathrm{MgO}/\mathrm{Ag}(100)$ as a function of temperature and magnetic ...

Magnetic relaxation in single-ion magnets formed by less-studied ...

Advances in single-ion magnets based on Ce, Nd, Gd, Ho, Tm and Yb are reviewed thoroughly. The strategies for designing an SIM are summarised along with the ...

Reading and Writing Single-Atom Magnets - Zora.uzh.ch

Here we address the magnetic switching of individual Ho atoms on MgO, which we control by current pulses and detect by changes to the tunnel magnetoresistance ...

Understanding magnetic relaxation in single-ion magnets with high ...

Indeed, their magnetic bistability enables one to encode a bit of information in a single molecule [3,4]. ... Sketch of the relaxation mechanisms ...

[PDF] Reading and writing single-atom magnets | Semantic Scholar

The reading and writing of the magnetism of individual Ho atoms on MgO are demonstrated, and it is shown that they independently retain their magnetic ...

To date, the smallest individually addressable bistable magnetic bits on surfaces consist of 5-12 atoms. Long magnetic relaxation times were demonstrated in ...

Engineering atomic-scale magnetic fields by dysprosium single ...

Surface-supported single atom magnets offer such possibilities, where long temporal and thermal stability of the magnetic states can be achieved ...

A reaction-coordinate perspective of magnetic relaxation

One property in particular, magnetic relaxation, is a complicated physical phenomenon that is scarcely treated in undergraduate coursework.

Unconventional Spin Relaxation Involving Localized Vibrational ...

We investigate the spin relaxation of Ho single atom magnets on MgO/Ag(100) as a function of temperature and magnetic field.

Unconventional Spin Relaxation Involving Localized Vibrational ...

We investigate the spin relaxation of Ho single atom magnets on MgO=Ag(100) as a function of temperature and magnetic field. We find that ...

Reading and writing single-atom magnets for Nature - IBM Research

Long magnetic relaxation times have been demonstrated for single lanthanide atoms in molecular magnets, for lanthanides diluted in bulk ...

A perspective on surface-adsorbed single atom magnets as atomic ...

Such a mechanism limits the magnetic stability of the Ho atoms and prevents their use as magnetic bits above 40 K. However, it is still not ...
