Below 20 K the g parameter of this signal is strongly temperature dependent. At about the same temperatures there is a ferromagnetic-like transition in the magnetic susceptibility. {\textcopyright} 1992 Taylor \& Francis Ltd.}, doi = {10.1080/13642819208215105}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84910921732\&doi=10.1080\%2f13642819208215105\&partnerID=40\&md5=f35c076928461ca8f6f1d39fc32ec3ca}, author = {Gamari-Seale, H. and Guskos, N. and Koufoudakis, A. and Kruk, I. and Mitros, C. and V.
