Interaction between magnetic molecules and two ferromagnetic electrodes of a magnetic tunnel junction (MTJ)

Spin state of a single-molecule magnet (SMM) creating long-range ordering on ferromagnetic layers of a magnetic tunnel junction – a Monte Carlo study

“…A dedicated study focusing on J mL and J mR has been published elsewhere. 22 The MTJMSD energy with different parameters was calculated using eqn (1). To simulate the effect of change in temperature, we varied thermal energy (kT) of the MTJMSD Heisenberg model in energy (U) eqn (1).…”

“…This paper investigates the effect of molecular spin state on the experimentally studied cross junction shaped MTJMSDs 15,16 with extended ferromagnetic electrodes beyond the molecular junction area. For this study, we have employed the Heisenberg Model 19 of MTJMSD that showed promising results in our prior MCS 20 . This paper provides new insights into the effect of molecular spin state and evaluates the properties of whole MSD.…”

“…The selection of this approach is based on the successful application of MCS, explaining the experimental results obtained from MFM and SQUID magnetometry. 22 This paper provides new insights into the effect of molecular spin state and evaluates the properties of the whole MTJMSD.…”

New value of old knowledge: sulphur-based GaAs surface passivation and potential GaAs application in molecular electronics and spintronics

“…This exchange coupling resulted in intriguing current suppression and a spin-dependent photovoltaic effect [23]. Recent molecular spintronics studies have indicated that molecules' ability to covalently bond to the electrode can be considered a tool to yield novel device behaviors [26,29,30,[56][57][58][59]. The following sections describe the basics of the GaAs surface and its interactions with S-like passivants.…”

“…The molecule was connected to GaAs and metal via a thiol(S) functional group. In addition to the published work, we also conceptualize tunnel junction-based molecular devices [21][22][23][24][25][26][27][28][29] utilizing GaAs as the electrode material (figure 1); further discussion about this approach is discussed elsewhere in this paper. Interestingly, the S-GaAs interaction has been extensively studied and may help in the burgeoning field of GaAs-based molecular devices.…”
