Magnetic Susceptibility of Yang's a Biradical from 4.2 to 293°K

High‐Temperature Ferromagnetism of a Discotic Liquid Crystal Dilutely Intercalated with Iron(III) Phthalocyanine

“…[ 3 ] However, many attempts have also been made to prepare RT or hightemperature ferromagnetic materials based on pure organic as well as organometallic compositions. In the approach using pure organic materials, many research groups have studied the ferromagnetism of diverse organic compounds, including galvinoxyl, [ 7 ] high-spin polycarbenes, [ 8 ] tanol suberate, [ 9 ] and conjugate conducting oligomers [ 10 ] with appropriate doping, in the hope that magnetism could be achieved through ferromagnetic coupling between the organic radicals. However, they did not show any magnetic long-range order at RT, although it was claimed that some of them [ 11 ] were ferromagnetic at very low temperatures.…”

“…These are fairly large in magnitude considering that the highest spin state of Fe(III) is at best S = 5/2, leading to a saturation value of the magnetization of 5 μ B . The remanent magnetization of 0.2 μ B is also reduced to (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) μ B /Fe(III)Pc. When we compare these values with that of (3-5) μ B /Mn for the typical group III-V spintronics spectra consist of two major parts.…”

RCNSSS+: A novel class of stable sulfur rich radical cations

“…The most abundant and well-characterized classes include nitroxide and nitronyl nitroxide [16][17][18][19], verdazyl [20][21][22][23], and phenoxyl [24][25][26][27] radicals (Chart 2). By comparison, far fewer examples of radicals based on third row elements are known, and those that exist are often air sensitive and prone to dimerization in the solid state.…”

Coercivity Control of Variable-Length Iron Chains in Phthalocyanine Thin Films

“…Historically, one of the first predicted organic ferromagnets was galvinoxyl, which has a measured CurieWeiss constant of 11 K based on susceptibility measurements [9][10][11]. Unfortunately, galvinoxyl undergoes a structural phase transition at around 90 K, such that it is impossible to measure magnetization curves for this material.…”
