Engineering the magnetic coupling and anisotropy at the molecule–magnetic surface interface in molecular spintronic devices

A challenge in molecular spintronics is to control the magnetic coupling between magnetic molecules and magnetic electrodes to build efficient devices. Here we show that the nature of the magnetic ion of anchored metal complexes highly impacts the exchange coupling of the molecules with magnetic substrates. Surface anchoring alters the magnetic anisotropy of the cobalt(II)-containing complex (C...

Magnetic compounds for improving spintronic applications

I wrote this thesis by myself and used none but the indicated resources. Text and figures were partly taken from corresponding publications, which originate directly from this work.

Proposal for a spintronic femto-Tesla magnetic field sensor

We propose a spintronic magnetic field sensor, fashioned out of quantum wires, which may be capable of detecting very weak magnetic fields with a sensitivity of ∼ 1 fT/ √ Hz at a temperature of 4.2 K, and ∼ 80 fT/ √ Hz at room temperature. Such sensors have applications in magnetometry, quantum computing, solid state nuclear magnetic resonance, magneto-encephalography, mine detection, ground in...
