Giant magnetoresistance of (001)fe/(001)cr magnetic superlattices
Baibich, Mario Norberto; Broto, Jean Marc; Fert, Albert R.; Dau, F. Nguyen van; Petroff, Frédéric; Etienne, P.; Creuzet, G.; Friederich, A.; Chazelas, J. (1988) [Artículo de periódico]We have studied the magnetoresistance of (001)Fe/(001)Cr superlattices prepared by molecular-beam epitaxy. A huge magnetoresistance is found in superlattices with thin Cr layers: For example, with tCr=9 Å, at T =4.2 K, the ... -
Hopping conductivity in one-dimensional Ca/sub 3/Co/sub 2/O/sub 6/ single crystals
Raquet, Bertrand; Baibich, Mario Norberto; Broto, Jean Marc; Rakoto, Harison; Lambert, Sébastien; Maignan, Antoine (2002) [Artículo de periódico]We studied the electronic conductivity and magnetic properties of quasi-one-dimensional Ca₃Co₂O₆ single crystals. The results evidence a variable range hopping conductivity with temperature-induced crossover between ...
