Study of magneto-electric (M-E) coupling effect in spin triangle based metal (III) carboxylate [M3O(O2CPh)6(py)3] ClO4.py (M= Fe, Ga) molecular magnet. — •Balwant Singh Chauhan1, Ratnamala Chatterjee1, AK Boudalis2, and P Turek2 — 1Department of Physics, IIT Delhi, Hauz Khas, New Delhi 110016, India — 2Institut de Chimie de Strasbourg (UMR 7177, CNRS-Unistra), Université de Strasbourg, 4 rue Blaise Pascal, CS 90032, Strasbourg, 67081, France
Materials with magneto-electric coupling effect having coupled magnetic and electric properties have potential applications in energy efficient data storage and other multifunctional device technology. In recent literature organic molecules like molecular magnets/molecular ferroelectric materials are being explored for their possible novel magneto-electric characteristics. In this context, a work by French group [1] on Fe spin triangle based metal carboxylates [F3O(O2CPh)6(py)3]ClO4.py have attracted a lot of attraction. In this work, we would clearly demonstrate a correlation between dielectric and magnetic properties of the [F3O(O2CPh)6(py)3]ClO4.py complex. The highlight of the work is the observation of direct ME coupling coefficient in this molecular magnet complex. A comparison of the same with nonmagnetic Ga(III) complex will be discussed too.
