Our article Polyanisotropic Magnetoelectric Coupling in an Electrically Controlled Molecular Spin Qubit (J. Am. Chem. Soc., 2019, 19765-19775 DOI: 10.1021/jacs.9b09101) is featured at the front cover of issue 50 of JACS.

Following our previous work demonstrating the magnetoelectric coupling of spin triangles in static electric fields, our most recent publication in JACS shows how we can use pulsed electric fields to achieve the coherent manipulation of spin triangles. In this work we show that the magnetoelectric coupling is highly anisotropic with respect to the molecular orientation inside the magnetic and electric fields.

Brief  intro

The SMM evaluator tool (SMM-ET) calculates the ac susceptibility and hysteresis loop curves of an SMM, using the following inputs:

Inputs

1) Relaxation time parameters that correspond to Orbach, Raman, Direct and QTM processes.

2) The magnetic behaviour of the SMM during dc χ vs T and M vs H experiments. This behaviour can be imported in two ways:

This work presents our comparative pulsed EPR studies of two molecular spin qubits, consisting of iron(III) and chromium(III) triangles. Fe₃ exhibits very broad spectra due to the effect of Dzyaloshinskii-Moriya interactions and this work assesses the degree to which these broadenings accellerate spin decoherence due to spectra diffusion.

Earlier this year I was very honored to be invited by the organisers of the XVII International Feofilof Symposium (Ekaterinburg, 23-28 September 2018) to present the findings of the CHIRALQUBIT project. It was a wonderful opportunity to interact with the Russian community of optical and magnetic resonance spectroscopy and to visit Russia for the first time.

The EPR detection of magnetoelectric coupling has just been published by Chemistry, a European Journal in our article which recently appeared in early view as a "Hot paper".

This work shows how the spins of magnetic triangles inetarct with external elctric fields, a feature that could lead to their electric control, and one of the key objectives of the CHIRALQUBIT project.

We are very excited that our work on magnetic Ionic Liquids was higlighted at the weekly general public journal "Ebdo". Many thanks to the editors for their interest!

The article "The paramagnetic absorption of a solution in parallel fields" appeared in English (Journal of Physics, 1944, XIII:6, 377-380) and in Russian ("Парамагнитная абсорбция в растворах при параллельных полях", Журнал эксперимент. и теоретич. физики., 1945, 15:6, 253-257) and descibed the parallel-field EPR studies of MnSO4 solutions.

This paper was followed by perpendicular-field studies published on a subsequent issue of the same journal and can be found here.

We are delighted that our recent work on the development of liquid magnetic materials was featured at the CNRS website, En direct des laboratoires de l'institut de Chimie.

In July 1944, Evgeny Konstantinovich Zavoisky (Евгений Константинович Завойский) submitted his observations on the paramagnetic relaxation of solutions of manganese(II) salts, under magnetic fields using microwave radiation (actually, he used 12 and 5.3 MHz frequencies, which can also be considered radiowaves).
