Control of Coercivity in Organic‐Based Solid Solution V<i>_x</i>Co_1–<i>_x</i>[TCNE]₂·<i>z</i>CH₂Cl₂ Room Temperature Magnets

Abstract

Solid solutions of V x Co 1– x [TCNE] 2 composition have been prepared from the reaction of V(CO) 6 and Co 2 (CO) 8 in dichloromethane. All magnetically order above 280 K for x &gt; 0.05 and their coercivity increases with decreasing x , reaching a maximum of 270 Oe for x = 0.3 (see Figure). Hence, the magnetic properties of this magnet can be finely tuned via a synthetic organic chemistry methodology.
