Y. Uwatoko et al., GIANT MAGNETORESISTANCE OF CO CU SUPERLATTICE UNDER HIGH-PRESSURE/, Journal of magnetism and magnetic materials, 144, 1995, pp. 583-584
The magnitude of giant magnetoresistance (GMR) of the (Co10 Angstrom/C
u10 Angstrom)(15) superlattice has been measured up to 20 kbar. It is
found that the electrical resistivity rho decreases with increasing pr
essure at room temperature, having the rate rho(-1)partial derivative
rho/partial derivative P = -22 X 10(-3) kbar(-1). The magnetoresistanc
e (MR) ratio Delta rho/rho(s) at 4.2 g slightly decreases with increas
ing pressure. The saturation field H-s also decreases with increasing
pressure.
