We present two-terminal magnetotransport measurements on single-wall carbon nanotube devices, where one or two of the terminals are ferromagnetic. Both ferromagnetic semiconductor [(Ga,Mn)As] and metal (Fe) contact materials have been investigated. In both types of devices we have observed strong hysteretic magnetoresistance below 30 K. The magnetoresistance features develop into large peaks and dips at subkelvin temperatures and they are present even with only one ferromagnetic terminal.
