The spin transition of Fe2+ ions in the mononuclear compound cis-bis(thiocyanato)-bis(N-2'-pyridylmethylene)-4-(aminobiphenyl)-iron(II) is studied by electron paramagnetic resonance (EPR) of Mn2+. In cooling the compound down to the temperature range

Nanoparticles of maghemite (γ-Fe 2 O 3 ) are formed in a sol–gel silicate glass with a molar ratio Fe/Si of 2% by a treatment at 1000°C for 6 h. Electron paramagnetic resonance spectrum at 300 K shows a relatively narrow sharp line at g eff ≈2.

Spin transition polymer with a large hysteresis around room temperature: optical response and electron paramagnetic resonance

Autor: C. Cantin, Janis Kliava, Y. Servant, Hervé Daubric, Olivier Kahn, Line Sommier

A polymer compound has been studied by optical response and electron spin resonance (EPR) using and as dopants and paramagnetic probes. The transition between low-spin (LS) and high-spin (HS) states of ions occurs with a broad hysteresis loop around
