Enhanced room-temperature positive magnetoresistance of a-C:Fe film

Electrical and magnetic properties of electrodeposited nickel incorporated diamond-like carbon thin films

“…Host et al [43] reported the dependence of room temperature saturation magnetization, remnant magnetization and coercive field of graphite encapsulated Ni and Co particles on annealing temperature. Tian et al [44] reported magneto-resistance measurements on Fe-doped amorphous carbon films prepared by pulsed laser deposition method. Sedlackova et al [45] reported the correlation of structural electronic and mechanical properties of carbon-nickel composite thin films with variation of deposition temperature where the films were grown by dc magnetron sputtering.…”

High definition conductive carbon films from solution processing of nitrogen-containing oligomers

“…with sputtering [9], pulsed laser deposition [10], electron cyclotron resonance [11], filtered cathodic vacuum arc process [12,13] and plasma enhanced chemical vapor deposition [14,15] as some more detailed examples. PVD and CVD techniques are used to produce thin and ultra-thin coatings of inorganic elements (metals, semiconductors, ceramics) as well as carbon and some organic compounds [16].…”

Band engineering magneto-resistance effect in Co:a-C films

“…Recently, the magneto-properties of carbon-based materials have been intensively studied to determine their suitability for use in carbon spintronic devices [9]. In particular, observations of positive magnetoresistance (PMR) in transition metal (TM)-doped carbon have attracted much attention owing to the considerable MR ratio of such systems [5,6]. Unlike group IV amorphous semiconductors which are constructed from disordered tetrahedral sp 3 bonds, amorphous carbon (a-C) typically contains a mixture of sp 2 and sp 3 bonds [10,11].…”

“…Amorphous carbon (a-C) films have been regarded as promising candidate materials for various optical, magnetic, and electrical applications [1][2][3][4][5][6][7][8]. Recently, the magneto-properties of carbon-based materials have been intensively studied to determine their suitability for use in carbon spintronic devices [9].…”
